Answer:
Step-by-step explanation:
V of a cube is s^3
V = 512
s = cube root of (V)
s = cube root of 512 cm^3
s = 8
The area of one face of the cube is s^2
s = 8
Area 1 face = 8^2
Area of 1 face = 64 cm^2
Answer:
<u>x = -8</u>
4x + 8 = 2x - 8
3x + 4 = 2x - 4
2x + 16 = x + 8
x - 1 = 2x + 7
17x + 36 = 16x + 28
13x + 2 = 12x + 11
.......
(this is infinite)
As long as it cancels out to x = -8
The Pythagorean theorem can be used for this.
.. (tip distance)² = (shadow length)² + (tree height)²
.. tree height = √((tip distance)² -(shadow length)²)
.. tree height = √((60 ft)² -(40 ft)²) = √(2000 ft²)
.. tree height ≈ 44.72 ft
Answer:yes
Step-by-step explanation:
is so yes so if the 50 it was the 40 so then they it yes
Answer:
Step-by-step explanation:
because 8(8)=64 and 8 is the positive square root of 64.
because 17i(17i)=289i^2=-289(-1)=-289.
