Answer:
The answer to your question is:
1) x = 4
2) x = -2
Step-by-step explanation:
a) (x-3)² = x^{2} - 10x +25
x² - 6x + 9 = x² - 10x + 25
10x - 6x = 25 - 9
4x = 16
x = 4
b)
(x+4)³ = x³ + 12x² - 16x
x³ + 3(x²)4 + 3x(16) + 4³= x³ + 12x² - 16x
x³ + 12x² + 48x + 64 = x³ + 12x² - 16x
48x + 64 = 16x
48x - 16x = -64
32 x = -64
x = -64/2
x = -2

Answer:
2138.85
Step-by-step explanation:
2250 decreased by 2% is
2% of 2250 subtracted from 2250
That’s
2% /100% x 2250
0.02 x 2250
45
So, decrease = 2250 - 45
= 2205
Now 2205 decreased by 3%
3% of 2205
3% /100% x 2205
0.03 x 2205
66.15
Decrease = 2205 - 66.15
= 2138.85
