4(x + 3)² = 25(x - 2)²
Square root both sides:
2(x+ 3) = 5(x - 2)
Distribute 2 and 5:
2x + 6 = 5x - 10
Take away 2x from both sides:
6 = 3x - 10
Add 10 to both sides:
16 = 3x
Switch sides:
3x = 6
Divide both sides by 3:
x = 2
Answer: x = 2
Answer:
1
Step-by-step explanation:
f(x) = x² + 3x
g(x) = 5x + 2
f(3) = 3² + 3 x 3
f(3) = 9 + 9
f(3) = 18
g(3) = 5(3) + 2
g(3) = 15 + 2
g(3) = 17
(f - g)(3) = 18 - 17
(f - g)(3) = 1.
Answer:
The two numbers are 21 and 9
Step-by-step explanation
(15+6) minus (15-6) gives a difference of 12
21- 9 = 12

Answer: H = 2W - 3
Twice the width is 2W and 3 millimeters less is - 3,
So your height of the rectangle is
2W - 3
