if its wrong that means you didn't explain it correct tell me if its wrong and ill solve it correctly if you say what's the width, length and height the answer is down below.
Answer: 236 in²
Lets say two numbers are x and y
x+y=70-----------------------eq1
x=4y--------------------eq2
4y+y=70
5y=70
y=70/5
y=14
then x=4*14
x=56
14/175 x 100 = 8%
answer is A. 8 (first choice)
The answer is 2, simply because you need to make that negative sign a positive sign. To do that you will need to flip the numerator and denominator. Meaning that it will be 4/1 now. By doing this your exponent became positive! So if your teacher just wanted you just rewrite it, it would be (4/1)^1/2, but if you were to evaluate that, it would be 2
We use BEDMAS and we go from left to right
Therefore; 1. 9+34 = 43
2. 43+5452 = 5495
3. 5495 -49349 = -43854
4. -43854+4 = -43850
Final Answer is - 43' 850.
