Answer:

  2a. (360x +495)/(8x +11) = 45

  2b. 2((8x+11) +45) = 16x +112

Step-by-step explanation:

a) The area is the product of length and width.

  A = LW

We are given ...

  W = 8x +11

  A = 360x +495

The value of length can be found by solving for L:

  L = A/W

  L = (360x +495)/(8x +11)

The long-division solution to this is shown in the attachment.

  L = 45 . . . . simplified expression for length

__

b) The perimeter of the tank is twice the sum of length and width:

  P = 2(L +W)

Substituting the values for L and W, this is ..

  P = 2(45 +(8x +11)) . . . . expression for length of edge seal

  P = 2(8x +56)

  P = 16x + 112 . . . . . . simplified expression for seal length

9x^2 sqrt2x ahhhh

Answer:

chfdhfjfhbdhfuthdhfuruu

Explanation:

The scale factor 3/2 is the same as 1.5

We multiply this by the perimeter 18 to get 18*1.5 = 27

The perimeter is 27 units.

This trick works because we're multiplying each length by 1.5, so ultimately the perimeter is multiplied by this same scale factor.

Answer:

I'm not completely sure but I think it's A E

Answer:

Step-by-step explanation:

We calculate terms in parentheses: +(3x-84-()), so:

3x-84-()

We add all the numbers together, and all the variables

3x

Back to the equation:

+(3x)

x=0/3

Answer: b

Step-by-step explanation:  y=3x−84.

y=3x−84

Answer:

b its a trinominal with a degree of 2

The polynomial, 3x - 4 + 5x², is a trinomial with a degree of 2.

An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

Given:

We have the polynomial,

3x - 4 + 5x²

To find the degree of a polynomial:

We take the highest powered variable, and the order of that variable is equal to the degree of the polynomial.

Here, the highest power is 2.

So, the degree is 2.

And the polynomial has three terms.

So, the polynomial is trinomial.

Therefore, it is a trinomial with a degree of 2.

Answer:

93 degrees

Step-by-step explanation:

First, you would need to observe the image and see where to start off. You can see that there is a triangle below the "?" and you would be able to get the answer if you can find the measures of the small triangle(because of vertical angles) So,

180-127= 53.

180-146=34.

Since the angles of a triangle adds up to 180 degrees, 53+34+x=180.

x=93

Now, just flip the angle around and "?" = 93 degrees.

Answer:  93 degrees

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

Explanation:

Let x be the question mark angle we want to find.

Let y be adjacent to the 127 degree angle

Let z be adjacent to the 146 degree angle.

Refer to the diagram below.

Note that in the diagram, I have a second copy of 'x' because the two x angles are vertical angles. Vertical angles are always congruent.

Let's find angle y

127+y = 180

y = 180-127

y = 53

Do the same for angle z

z+146 = 180

z = 180-146

z = 34

Then notice how,

x+y+z = 180

x+53+34

x+87 = 180

x = 180-87

x = 93

Answer:

a² + b² = 250

Step-by-step explanation:

Given

a + b = 20 ( square both sides )

(a + b)² = 20² , that is

a² + b² + 2ab = 400 ( substitute ab = 75 )

a² + b² + 2(75) = 400

a² + b² + 150 = 400 ( subtract 150 from both sides )

a² + b² = 250

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, a) and (x₂, y₂ ) = (1, b)

m = [tex]\frac{b-a}{1-0}[/tex] = b - a

y = (b - a)x + c

(a)

with coefficient of x being b - a

(b)

The line crosses the y- axis at (0, a ) ⇒ c = a

y = (b - a)x + a

Answer:

D is the correct answer

Step-by-step explanation:

it honestly depends on what the numbers are

for example, 12 -6, you would get 6.

but if the question is something like 4 -8, you'd have -4

Step-by-step explanation:

Expression = -5 + 2

Sum = -5 + 2 = 3

Answer:

a. 6(7) + 2(3)^2 = 60

b. (5(-18)/3)-2 = -32

c. (6(10))^2 - 10/5 = 3598

d. (1-3)(1+2) = -6

Answer:

RS = 43

Step-by-step explanation:

Since RT is the whole line, your total is 59. Since you have part of what RT is which is 16, subtract 16 from 59.

59 - 16 = 43

Answer:

1 3/4 lbs of skittles

Step-by-step explanation:

Easy way: 3lbs - 1 1/4lbs = 1 3/4lbs

Complex way:

(I'm assuming "1/1/4" means "1 1/4")

This is simply ~Subtraction~

The total is 3lbs(t) and 1 1/4 of that 3lbs is gummy worms(g). What is left of the 3lbs is skittles(s).

So we need to know what added to 1 1/4 equals 3.

Equation: t= 1 1/4 + s

Equation: t= 1 1/4 + s

We can replace (t) with 3 because we know this variable.

1. 3= 1 1/4 + s

To isolate the variable (s) we need to subtract 1 1/4 on both sides of the equation

2. 3(- 1 1/4)= 1 1/4(- 1 1/4) + s

The right side cancels out = 0 and the left = 1 3/4

3. 1 3/4= s

Flip it around for the traditional view

4. s = 1 3/4

In word form: Skittles equal 1 3/4 (don't forget to add lbs or pounds back into the final answer)
