Answer:
C. (3x2 - 10) (x - 2)
Step-by-step explanation:
3x^2 - 16x +20
Step 1: Sum = - 16x
Product = 60x^2
Step 2: Find 2 numbers that their sum is -16 and their product is 60. If you do that correctly, then you will get two numbers: 10 and -6
Step 3: Replace -16x with the two numbers found in step 2, then you will have; 3x^2 - 6x - 10x + 20
Step 4: Factorise the equation in step 3, like so;
(3x^2 - 6x)(- 10x + 20)
3x(x - 2) -10(x - 2)
(3x - 10)(x - 2)
To check if the answer is correct, expand the bracket: (3x - 10)(x - 2)
If the bracket is opened properly, you will get 3x^2 - 16x + 20
Answer:
15.9
Step-by-step explanation:
They each have $42 because 7 times 6 is 42 and combined they have $84 because 42 + 42=84.
Hello from MrBillDoesMath!
Answer: 13
Discussion:
Evaluate f(g(3)).
g(3) = 3^2 -4 = 5 so
f(g(3)) = f(5) = 3*5-2 = 15 -2 = 13
Thank you,
