Answer:
C
Step-by-step explanation:
To factorise the quadratic
Consider the factors of the constant term (- 39) which sum to give the coefficient of the x- term (- 10)
The factors are - 13 and + 3, since
- 13 × 3 = - 39 and - 13 + 3 = - 10, hence
x² - 10x - 39 = (x - 13)(x + 3) ← in factored form
x - 13 is a factor → C
Answer:
( x + 12 ) °
is your answer.
Step-by-step explanation:
you can see it !!!
12C3 means nCr
You have 12 items of which you want to choose 3 and the order in which you choose them does not matter.
n! 12! 12! 479001600
---------- = -------- = ------- = ----------------- = 220
(r!(n-r)! 3!(12-3)! 3!(9!) 21177280
F(g(x)) = 2(5x+1)-6 = 10x+2-6 = 10x-4
g(f(x)) = 5(2x-6)+1 = 10x-30+1 = 10-29
10x-4>10-29 because from f(g(x)) you subtract less quantity.
The answer to your question is C. I hope that this is the answer that you were looking for and it has helped you.
A: e and c are verticale angles
B: c and b are complementary angles
C: c and d are supplementary angles
Im not sure with d
E: e = 30, b=60, a=90, d=150
