Answer:

D 30 ft^2

Step-by-step explanation:

This figure is a trapezoid

The area of a trapezoid is given by

A = 1/2 (b1+b2) *h  where b1 and b2 are the lengths of the top and bottom

A = 1/2( 10+5) * 4

   = 1/2 (15)*4

   = 1/2(60)

   = 30 ft^2

For this case we have that by definition, the area of a trapezoid is given by:A = \frac {(B + b) * h} {2}

Where:

B: It is the major base

b: It is the minor base

h: It's the height

According to the data we have:

B = 10ft\\b = 5ft\\h = 4ft

Substituting:

A = \frac {(10 + 5) * 4} {2}\\A = \frac {15 * 4} {2}\\A = \frac {60} {2}\\A = 30

So, the area of the figure is 30 \ ft ^ 2

5x+4y=8

-5x from both sides, you get 4y=-5x+8
then you divide the equation by 4.

y=-5/4x+2

10x-4y=46

-10x from both sides and you get -4y=-10x+46
divide the whole equation by -4 and you get y=5/2x + -23/2 .

Which student solves and explains the equation correctly? Will choose brainliest.
-Dominant- [34]

Answer:

Jerry  is correct

Step-by-step explanation:

8^{x} = 512

this equation is asking 8 to what power is 512

Emma said the solution is x=3. Her explanation is 8 x 3 which would equal 24. This is not the correct answer.

Jerry's solution  is x = 3. His explanation is 8 x 8 x 8 which would equal 512. This is the correct answer.

Mel's solution is x = 8. Her explanation is 8 x 3 which equals 24. This is not the correct answer.

Victoria's solution is x = 8. Her explanation is 8 x 8 x 8 which would equal 512. However, her explanation is correct, her solution is not. 8^{8} = 16777216. That is what her solution is saying.
