Answer:
5^10 / 5^8 = 5^2 = 25 so the equation becomes 25 = (1/5) ^ n. This means that n = -2.
The answer is 35 pounds because,
56 / 8=7 so 5x 7 =35 pounds
Answer:
10x²+11-2x
Step-by-step explanation:
I hope you mean 7x²+8+5, not 7x²+8x+5.
We need to combine like terms. Anything with squared should be added together, et cetera.
(7x²+8+5)+(3x²-2x-2)
You can take out the parenthesis, because they don't matter in addition.
7x²+8+5+3x²-2x-2
Add the terms, step by step. Each bold pair needs to be added together.
7x²+8+5+3x²-2x-2
10x²+8+5-2x-2
10x²+11-2x
Now there's no more we can add together.
Answer:
460 in.^2
Step-by-step explanation:
Using the formula provided in the image: <em>SA = 2lw + 2lh + 2wh</em>
Length = 10 in.
Height = 12 in.
Width = 5 in.
2(10 * 5) + 2(10 * 12) + 2(5 * 12) = 100 + 240 + 120 = 460
Basically all you’re doing is plugging in the inputs to the equations and see if they’re correct.
5(3)+4(-3)=3 this proves to be true
2(3)-5(-3)=21 not 19
