A wall has an area of 40 ft. It’s height is 8 feet. Which equation could you use to find its width. Answers 40- w = 8
RideAnS [48]

8w=40

You get area by doing length x width. In this case, the “length” is the height. So you would need to figure out what you multiply 8 by to get 40.

Help!! Can someone explain this to me I’m not getting it.
chubhunter [2.5K]

Answer:

A. 99 sq cm

Step-by-step explanation:

Area of geometric shape

= 2 times the area of one triangle with base a and height c

+ 2 times the area of one triangle with base c and height b

+ Area of rectangle with dimensions a and c.

= 2 \times  \frac{1}{2} ac + 2 \times  \frac{1}{2} bc + ac \\  \\  = ac + bc + ac \\  \\  = 2ac + bc \\  \\  = 2(13)(3) + 7(3) \\  \\  = 78 + 21 \\  \\  = 99 \: sq \: cm

Bobby and his family went to the playground. The slide is 13
Nonamiya [84]

Answer:

it would be close to 12 ft im not 100% sure though the measurements are a little off

Step-by-step explanation:

hypotenuse is 13

then you have the adjacent = 7

13^2 = 169

7^2= 49

169-49=120

the square root of 121 is 11 wich is fairly close to 120(doesnt have one because its not exact)

there is two extra feet so 11 +2 is 13 but there  was a little less then 11 so i had sid roughly around 12

brainliest, please???
