Given sides of the triangle:

We know that the perimeter of a triangle is the sum of all the sides of a triangle.

Perimeter of the triangle,

= 3x^2 + 8 + 2x^2 + x + x - 3

= 3x^2 + 2x^2 + x + x + 8 - 3

= 5x^2 + 2x + 5

Therefore, the perimeter of the triangle is 5x^2 + 2x + 5. Hence, the option A is the correct answer.

Answer:

The width of a rectangular garden is x feet and its length is 5 feet more than twice its width. A 3-foot-wide path borders the inside of the garden on all sides, as shown in the diagram. Represent the total cost of paving the path at a rate of $2.45 per square foot and mulching the garden at a rate of $0.25 per square foot.

Combine the two functions to determine the total cost of paving the path and mulching the garden. To find the area to be paved, find the area of the garden excluding the inner portion; that is, subtract g(x) from f(x). If p(x) represents the area to be paved, then this is true:

p(x) = f(x) − g(x)

= (2x + 5x) − (2x2 − 13x + 6)

= 2x^2 + 5x − 2x^2 + 13x − 6

= 18x − 6

p(x) = 18x − 6

The cost of paving the path at the rate of $2.45 per square foot is $2.45p(x). The cost of mulching the garden at the rate of $0.25 per square foot is $0.25g(x). So, the total costs for paving the path and mulching the garden can be represented by this function:

$2.45p(x) + $0.25g(x)

= $2.45(18x − 6) + $0.25(2x^2 − 13x + 6)

= $(44.1x − 14.7) + $(0.5x2 − 3.25x + 1.5)

= $0.5x2 + $40.85x – $13.20.

Step-by-step explanation:

Edmentum answer

The area of the garden excluding the inner portion; that is, subtract g(x) from f(x). If p(x) represents the area to be paved, then we have p(x) = f(x) − g(x).

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The width of a rectangular garden is x feet and its length is 5 feet more than twice its width. A 3-foot-wide path borders the inside of the garden on all sides, as shown in the diagram. Represent the total cost of paving the path at a rate of $2.45 per square foot and mulching the garden at a rate of $0.25 per square foot.

Combine the two functions to determine the total cost of paving the path and mulching the garden. To find the area to be paved, find the area of the garden excluding the inner portion; that is, subtract g(x) from f(x). If p(x) represents the area to be paved, then this is true:

p(x) = f(x) − g(x)

= (2x + 5x) − (2x² − 13x + 6)

= 2x² + 5x − 2x² + 13x − 6

= 18x − 6

p(x) = 18x − 6

The cost of paving the path at the rate of $2.45 per square foot is $2.45p(x). The cost of mulching the garden at the rate of $0.25 per square foot is $0.25g(x). So, the total costs for paving the path and mulching the garden can be represented by this function:

2.45p(x) + 0.25g(x)

= 2.45(18x − 6) + 0.25(2x² − 13x + 6)

= (44.1x − 14.7) + (0.5x² − 3.25x + 1.5)

= 0.5x² + 40.85x – 13.20

Therefore, the total costs for paving the path and mulching the garden can be represented by the function is 0.5x² + 40.85x – 13.20.

Step-by-step explanation:

supplement means their addition is equal to 180°

since m<x and m<y are supplement then m<x+m<y=180

and <y supplement to <z (their addition equals to 180°)

since m<y and m<z are supplement then m<y+m<z=180

m<x+m<y= m<y+m<z

m<y cancelled

m<x= m<z

_________________

FOR EXAMPLE

Given that <x and <y are supplement

and <y and <z are supplement

if <x= 45°

that means that <y = 135°

so that <x +<y = 180°

45+135= 180 ✓

and <y and <z are supplement

m<y+ m<z = 180°

then m<z= 45°

m<x+m<y= m<y+m<z

m<x +135= 135+m<z

then m<x= m<z = 45°

Answer:

99/100

Step-by-step explanation:

First of all recall that

[tex]a^n\cdot b^n =(ab)^n[/tex]

Now we we will try to apply that formula for [tex]a=99/100[/tex] and [tex]b=100/99[/tex].

I'll do the first five problems to get you started.

===========================================================

Problem 1

Subtraction can be thought of as adding a negative.

So -3 - 6 is the same as -3 + (-6)

We can think of an example involving money

-3 means we're 3 dollars in debt. Then -6 means we go 6 dollars further into debt. Therefore, the total debt is -3 + (-6) = -9 so overall we're 9 dollars in debt.

===========================================================

Problem 2

When subtracting a negative, the two will cancel out to form a positive. This is because negatives are opposite in nature. Two opposites undo one another.

So with all that in mind, something like 10 - (-4) will become 10 + 4

===========================================================

Problem 3

It's the same idea as the previous problem, but we're dealing with different numbers of course.

===========================================================

Problem 4

We'll use the ideas mentioned in problem 1. There's not much further to explain here.

===========================================================

Problem 5

Refer back to either problem 2 or problem 3 for a similar example. The negatives will cancel to form a positive.

Step-by-step explanation:

Angles DUT and VUD sum to VUT. We can create an equation to model this.

DUT + VUD = VUT

Now, let's plug our values into the equation.

24x + 5 + 46 = 35x - 4

Simplify the left side.

24x + 51 = 35x - 4

Subtract 24x from both sides and add 4 to both sides.

55 = 11x

Divide both sides by 11.

Answer:

Number 3.14 is rational number

Answer:

a) language

b) 2/15

Step-by-step explanation:

For the first part, you can start by making the denominators same

you take the LCM of 3 and 5 which is 15

Language books are now 10/15 since you multiply the nominator and denominator by 5

While science books are 3/15

10/15 : 3/15 making it obvious that language books are more

if the remaining are math books then

total books - (language + science books) = math books

10/15 + 3/15 = 13/15 (non math books)

15/15 - 13/15 are math books making 2/15 of them math books

Answer:

See below.

Step-by-step explanation:

Cos O is positive in the first and 4th quadrants and sin O is negative in the 3rd and 4th quadrants.

So the answer is Quadrant 4.

cos^2 O = 1 - sin^2 O

= 1 - (-3/5)^2

= 16/25

So  cos O  is +√(16/25)

= 4/5.
