Times 4 because, 5 times 4 is 20, 20 times 4 is 80 and so on.
A
(X-7)(x-4) -> x^2 -11x + 28

Answer:
800
Step-by-step explanation:
(2x) + 11 < 44
x is multiplied by two because we are looking for twice of x. 11 is added to the 2x because we are looking for eleven more than the sum of twice of x. Since 2x + 11 is less than 44, we use the lesser than ( < ) symbol.
Answer:
the right answer is 18 and under for part a for part b the answer is 45 -64
