Answer: a = 8
Step-by-step explanation:
use the equation a^2 + b^2 = c^2
c = 17, b = 15
a^2 + 15^2 = 17^2
a^2 + 225 = 289
a^2 = 64
a = 8
1. C.
The rule of powers is that when a parenthesis is raised to a power, you multiply the two numbers. Since it is being raised to the second power, it needs to have a 10 in the parenthesis. That would make 20.
2. B
Firstly 10^2 = 100, so we know that the number must be 10. That leaves us with just A and B. Then we know the same thing from the previous equation, that they need to be multiplied together.
Answer:
3+2x
Step-by-step explanation:
Distribute the equation out.
1/4(12+8x)
(1/4*12)+(1/4*8x)
Multiple those out to get a new equation
3+2x
You cannot add those together because of the variable. Theres no way of knowing what x equals so this is as far as you can go therefor making the answer 3+2x
You can find the dimensions of the model and plug them into the formula for volume (length x width x height)
