a. factor A = x^2 -30x + 225 = (x - 15)(x - 15)
side length =<u> (x - 15)</u>
b. add (x - 15) four times = 4(x - 15) =<u> 4x - 60</u>
Answer:
x=1
Step-by-step explanation:
3(x+2) - 4 = 2(x-1) +5
Distribute
3x +6 -4 = 2x -2 +5
Combine like terms
3x +2 = 2x +3
Subtract 2x from each side
3x-2x +2 = 2x-2x+3
x+2 =3
Subtract 2 from each side
x+2-2 = 3-2
x=1
The answer is 3x 2y of the questions
