Answer:
True
Step-by-step explanation:
Kilo means 1,000 so kilometers means 1,000 meters. If you don't know prefixes it might be kind of confusing because centimeters doesn't mean 100 meters so I'll leave something here.
Kilometers = 1000 meters
1 meter = 10 decimeters
1 decimeter = 10 centimeters
1 centimeter = 10 millimeters
If I have time later I'll attach a visual that could help.

2 ones are equal to 0 tens
Answer:
V = 112
Step-by-step explanation:
Volume = Area of the base x height, so area of the triangle is 1/2(8)(4) = 16
Volume = 16 x 7 = 112
Answer:
a). 8(x + a)
b). 8(h + 2x)
Step-by-step explanation:
a). Given function is, f(x) = 8x²
For x = a,
f(a) = 8a²
Now substitute these values in the expression,
= ![\frac{8x^2-8a^2}{x-a}](https://tex.z-dn.net/?f=%5Cfrac%7B8x%5E2-8a%5E2%7D%7Bx-a%7D)
= ![\frac{8(x^2-a^2)}{(x-a)}](https://tex.z-dn.net/?f=%5Cfrac%7B8%28x%5E2-a%5E2%29%7D%7B%28x-a%29%7D)
= ![\frac{8(x-a)(x+a)}{(x-a)}](https://tex.z-dn.net/?f=%5Cfrac%7B8%28x-a%29%28x%2Ba%29%7D%7B%28x-a%29%7D)
= 8(x + a)
b).
= ![\frac{8(x+h)^2-8x^2}{h}](https://tex.z-dn.net/?f=%5Cfrac%7B8%28x%2Bh%29%5E2-8x%5E2%7D%7Bh%7D)
= ![\frac{8(x^2+h^2+2xh)-8x^2}{h}](https://tex.z-dn.net/?f=%5Cfrac%7B8%28x%5E2%2Bh%5E2%2B2xh%29-8x%5E2%7D%7Bh%7D)
= ![\frac{8x^2+8h^2+16xh-8x^2}{h}](https://tex.z-dn.net/?f=%5Cfrac%7B8x%5E2%2B8h%5E2%2B16xh-8x%5E2%7D%7Bh%7D)
= (8h + 16x)
= 8(h + 2x)
