Answer:

B) 110.92 u²

Step-by-step explanation:

to find the surface area, find the area of each side and add them together.

here are all 6 sides:

4.5 * 6.8

4.5 * 6.8

4.5 * 2.2

4.5 * 2.2

2.2 * 6.8

2.2 * 6.8

4.5 * 6.8 = 30.6

4.5 * 6.8 = 30.6

4.5 * 2.2 = 9.9

4.5 * 2.2 = 9.9

2.2 * 6.8 = 14.96

2.2 * 6.8 = 14.96

30.6 + 30.6 + 9.9 + 9.9 + 14.96 + 14.96

110.92

Answer:

The expression x² + 8x + 7 can be factored out as (x + 7)(x + 1).

Step-by-step explanation:

You can see how this factors by looking at the last term, and the coefficient of the second term.  You need to find two numbers that multiply to make seven, and add to make eight.

Because seven is a prime number, this becomes very easy.  If this works at all, the numbers must be seven and one.

And lo, if you check, seven and one do indeed add up to be eight, so that's what we need to use.  Let's do it:

x² + 8x + 7

= x² + x + 7x + 7

= x(x + 1) + 7(x + 1)

= (x + 7)(x + 1)

Answers

Answer:

the missing side is √65

Step-by-step explanation:

a^2 + b^2 = c^2

4^2 + 7^2 = c^2

16 + 49 = c^2

65 = c^2

√65 = √c^2

√65 = c

you’re going to have to find the PT of the smaller triangle first , a2=b2+c2

4 squared = 2 squared + c
16= 4+ c
c squared =12
c=3.464

now that you’ve found c , u have to move on to the bigger triangle

a squared= 7 squared + 3.464 squared
a squared= 49+ 12
a squared = 61
a= 7.8

Answer:

a) 94°

Step-by-step explanation:

shape is a 5-sided polygon, known as a pentagon

number of degrees inside can be found by taking the number of sides (5), deducting 2 (3) and then multiplying by 180°.

Therefore there are 540° altogether.

add all like terms for all five angles:  24x - 12 = 540

                                                             24x = 552

                                                               x = 23

m∡P = 4(23) = 2

         = 92 + 2

Anne decided to build a fence around her 15 feet long flower bed. How many feet of fencing should she buy if the width of the flowerbed is 4/5 the length?

Answers

Answer:

[tex]54[/tex] feet

Step-by-step explanation:

Length of the flower bed [tex]=15[/tex] feet.

Width of the flower bed is [tex]\frac{4}{5}[/tex] the length.

So, width [tex]=\frac{4}{5}\times 15=4\times 3=12[/tex] feet.

To find the length of the fencing, we need to find the perimeter of the flower bed.

Perimeter of a rectangle [tex]=2(\textrm{length} + \textrm{width})[/tex]

So, perimeter of the flower bed [tex]=2(15+12)=2\times 27 = 54[/tex] feet.

Hence, [tex]54[/tex] feet of fencing is required for the flower bed.

Linear Equation, Need Solved Asap <3

Answers

Step-by-step explanation:

y = 5x - 4

When x = 0, y = 5(0) - 4 = -4.

When x = 1, y = 5(1) - 4 = 1.

When x = 2, y = 5(2) - 4 = 6.

The 3 ordered pairs we have are (0,-4), (1,1) and (2,6).

We now check the point (-5,-29):

(-29) : 5(-5) - 4

-29 : -25 - 4

-29 : -29 => -29 = -29.

Since Left hand side = Right hand side, the point (-5,-29) is a solution.

Answer:

1. (1,1) (2,6) (3, 11)

2. Yes

Step-by-step explanation:

1. 5(1)-4 = 5-4 = 1

5(2)-4 = 10-4 = 6

5(3)-4 = 15-4 = 11

(I just chose 3 simple x values and plugged them into the equation to get the y values then wrote it as an ordered pair)

2. 5(-5)-4 = -25-4 = -29

-29 = -29

(Same as number 1 but I used the given x value then I checked if the y value I got matched the ordered pair)
