A=1/2bh
A=1/2(36)(41.5)
A=747 square feet
Yep they do, because if you plug in y for both equations, you get x=0. To find y, plug in 0 for either equation to get -7. (0,-7) should work for both equations since the intersection point is the point where both equations meet.
Answer:
B duh
Step-by-step explanation:
Hey There! I can help you by explaining how to solve it but not answering sorry! Anyhow, To find the volume of a square based pyramid I suggest you start with the square and do L x W. Than Solve the triangles by using formula 0.5 * b * h. Hint: On the bottom triangle use 8cm from the square with the 3.8cm. Hope you now understand and can find the answer!

exponents
c^0.5
so 0.5=1/2 and if you have
x^(z/t)=
![\sqrt[t]{x^z}](https://tex.z-dn.net/?f=%20%5Csqrt%5Bt%5D%7Bx%5Ez%7D%20)
so
c^1/2=
![\sqrt[2]{c^1} or \sqrt{c}](https://tex.z-dn.net/?f=%20%5Csqrt%5B2%5D%7Bc%5E1%7D%20or%20%20%5Csqrt%7Bc%7D%20%20)
so
multiplication
-9 times √c is the answer or more commonly written as
-9√c
