Step-by-step explanation:
3x³ - 4x² - 28x - 16
= (x + 2)(Ax² + Bx + C)
= Ax³ + (2A + B)x² + (2B + C)x + 2C.
By Comparing Coefficients, we have:
Solving them will give A = 3, B = -10 and C = -8.
Hence 3x³ - 4x² - 28x - 16
= (x + 2)(3x² - 10x - 8)
= (x + 2)(3x + 2)(x - 4).
The answer is f(x) = (x + 2)(3x + 2)(x - 4).
Answer:
40.35
First find the discount
97 * 60%
97 *.6 = 58.2
Subtract the discount to find the new price
97-58.20 =38.80
Next find the tax
38.80 * 4%
38.80 * .04
1.55
We add the tax to the sales price
38.8+1.55
Answer 145°
( 5x+5 ) + 40° = 15x - 5
[ Reason : exterior extended angle of a triangle is always equal to the sum of two non adjacent interior angles ]
i.e, x= 10°
put this value of x on <PGF
= 15x - 5
= 15 * 10 - 5
=145°

- order from lowest to highest
15, 16, 17, 18, 19, 20, 20, 20, 22, 23, 25, 25
- now find the number in the middle
15, 16, 17, 18, 19, 20, <u>20</u>, 20, 22, 23, 25, 25
