Answer:

Esther didn't divide the area of the faces by 2.

The correct surface area is 72 cm^2

Step-by-step explanation:

Esther didn't divide the area of the faces by 2.

The correct surface area is:

(4 * 4) + 4((4 * 7)/2)

16 + 4(28/2)

16 + 4(14)

16 + 56 = 72 cm^2

gizmo_the_mogwai [7]

Answer:

<h2>The answer is 1</h2>

Step-by-step explanation:

The slope of the line between two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}

where

(x1 , y1) and (x2 , y2) are the points

From the question is points are

(8, 1) and (-1, 10)

Substitute the values into the above formula and solve for the slope

That's

m =  \frac{10 - 1}{8 + 1}  \\  =  \frac{9}{9}   = 1

We have the final answer as

<h3>1 </h3>
