you just find the surface area for each rectangle/square and then add them together

5x8=40

25x5=125

8x25=200

5x25=125

8x25=200

add those numbers and you get 730 :)

What are the solutions of x^2=8-5x?

Aleksandr [31]

Answer:

x = (-5 ± √57) / 2

Step-by-step explanation:

x² = 8 − 5x

x² + 5x − 8 = 0

Solve with quadratic formula:

x = [ -b ± √(b² − 4ac) ] / 2a

x = [ -5 ± √(25 − 4(1)(-8)) ] / 2

x = (-5 ± √57) / 2

Toski is building a room that is 18 feet long and 14 feet wide. Construct a scale drawing of the shed. Use a scale of inch = 2 f

AURORKA [14]

Answer:

Option A is the answer

Step-by-step explanation:

Toski is building a room having length = 18 feet

Width of the room = 14 feet

Scale has been given as 1 inch = 2 feet

∵ 2 feet = 1 inch

∴ 1 feet = $\frac{1}{2}$ feet

∴ 18 feet length of the room = $\frac{18}{2}=9$ inches

Similarly 14 feet width of the room = $\frac{14}{2}=7$ inch

Now we count the small blocks in the given options.

Option A has 9 blocks or 9 inches as the length of the room and 7 blocks or 7 inches as the width of the room.

Option A is the answer.
