You'll have to substitute all the y's by 18, so our expression will stay like this:
18 - 2 =
16 = final answer

(x+y)^2 = (x+y)(x+y) = x*x +x*y +y*x +y*y = x^2 + 2xy +y^2 so what not equal
x^2 +y^2

Answer:
(8x - 9y)2
Step-by-step explanation:
64x2−144xy+81y2
Equation at the end of step 1:
((64 • (x2)) - 144xy) + 34y2
The Equation at the end of step 2:
(26x2 - 144xy) + 34y2
Step 3:
(8x - 9y)2
Answer:
(8x - 9y)2
Answer:
V = 330
Step-by-step explanation:
To find the volume of a pyramid use this equation:
l = length
w = width
h = height
Lets assign each of these variables to what is in the picture:
l = 18 in
w = 5 in
h = 11 in
Now, plug these into the equation and solve:
Distribute the numerator
V = 330
Thus, the exact volume of the pyramid is 330 .
Hope this helps!!
