Answer:what grade are you in?
Step-by-step explanation:
Answer:
x = sqrt(32)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+ b^2 = c^2
7^2 + x^2 = 9^2
49+x^2 = 81
Subtract 49 from each side
x^2 = 81-49
x^2 =32
Take the square root of each side
sqrt(x^2) = sqrt(32)
x = sqrt(32)
Answer
Step-by-step explanation:
There were actually gaps of triangles in between the slabs and the sphere.
This could cause a decrease inthe volumes. The 2d shape is a triangle but the 3d shape is the cone.

Answer:
see below
Step-by-step explanation:
The applicable properties of exponents are ...
(a^b)^c = a^(bc)
(a^b)(a^c) = a^(b+c)
(a^b)/(a^c) = a^(b-c)

Please note that ...

That is, since the outside exponent is even, the sign is immaterial. This is also true for the other expression containing -2. The result is positive.
Answer:
Length = 42, Width = 25
Step-by-step explanation:
You write out the equation for the length, which is L=2w-8 (Length is L and width is W) You substitute in the length in the original equation, 2L + 2W = 134 ( I got this equation from knowing that 2 lengths plus 2 widths equals the perimeter, 134.) Substitute 2w-8 for L, you're left with 2(2w-8) + 2w = 134. Simplify further, you have 4w-16+2w=134. Once you're done, you have W=25. Plug that back into the original equation, then solve. L = 2(25)-8, L=42.
