Answer:
(x-3)(x-7)
Step-by-step explanation:

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.
NUMBER 3 :
150 feet / 15 = 10 units
120 feet / 15 = 8 units
So it will be 10 units by 8 units
NUMBER 4:
A) 525/4.2 = 120
The scale used was 120
B) 0.6 inches = 0.0152
525 / 0.0152 = 35 sheets tall
There are 45 eigths in 5 5/8 because 5*8 + 5 = 45
therefore 5 5/8 = 45/8
<span>two-thirds of eight is </span>8*2/3, which equals to16/3
