Your question is very vague, there is no multiple choice answers, your question lacks basically everything.
-2+(-2=4?
Answer:
n=6
Step-by-step explanation:
4n + 1= 25
Move constant to the right
4n=25-1
Calculate
4n=25-1
Then divide on both sides
H(-6) = 2(-6) + 5
h(-6) = -12 + 5
Solution: h(-6) = -7
C. 40
30x30=900
40x40=1600
total of 2500 take the square root and your left with 50 so everything balances out
