(A ∩ B) means "A intersection B". Your problem statement tells you the intersection contains
{3, 4}
Answer:
Missing constant: 100
Step-by-step explanation:
perfect square (a - b)^2 = a^2 - 2ab + b^2
In this case
20x = 2 * x * 10
and
10^2 = 100
so
(x - 10)^2 = x^2 - 20x + 100
Answer:
C
Step-by-step explanation:
Using the coefficients of each term and evaluating for h = - 4
- 4 | 1 - 7 - 7 20
↓ - 4 44 - 148
---------------------------
1 - 11 37 - 128 ← remainder
Quotient = x² - 11x + 37 , R - 128
Answer:
B. 13xy
hope this helps!
Explanation:
13*7 = 91
13*8 = 104.
Then you can pull one x and one y out. So 13*x*y
I think it is A
sorry if it is wrong!
