Answer:
A
Step-by-step explanation:
sum means addition
the problem says sum of -4x and 2 meaning -4x + 2
the word "is" right before 9 means equals 9
Answer: 14
Square both sides, getting you
2x-3=25
Add 3 to both sides
2x=28
Divide both sides by 2
x=14
Answer:
x = 10
Step-by-step explanation:
X = 10 because if you look at the 28 and 14, 14 is half of 28 so the ratio is 1:2 which would also work for the 20 so the answer is 10
