Answer:
The answer would be 161
Step-by-step explanation:
D
Answer:
672
Step-by-step explanation:
(1. Turn the percent into a decimal) 20% = 0.20 (2. Multiply 560 x 0.20 = 112) (3. Add 560 + 112)
x^2 - 2x - 3
1.1 Factoring x2-2x-3
The first term is, x2 its coefficient is 1 .
The middle term is, -2x its coefficient is -2 .
The last term, "the constant", is -3
Step-1 : Multiply the coefficient of the first term by the constant 1 • -3 = -3
Step-2 : Find two factors of -3 whose sum equals the coefficient of the middle term, which is -2 .
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -3 and 1
x2 - 3x + 1x - 3
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-3)
Add up the last 2 terms, pulling out common factors :
1 • (x-3)
Step-5 : Add up the four terms of step 4 :
(x+1) • (x-3)
Which is the desired factorization
