Answer: (2x+3)(x+3)
Step-by-step explanation:
Looking at this, you know that it must look something like
(? +3)(?+3) , because they must multiply to 9. The ?s must multiply to 2x^2, the most plausible values being 2x and x, ending us up with (2x+3)(x+3)
Ok well since it said “how much more we subtract 11-7=4
Your question is a difference of squares. both terms that need to be factored are squared. to solve take the square root of each put into two terms one of addition and one of subtraction.
anwser= (5x-9)(5x+9)
the reason this works is because when you foil you get
25x²-45x+45x-81
the middle terms cancel revealing
25x²-81
Answer:
80
Step-by-step explanation:
7x +3 = 5x + 25
2x + 3 = 25
2x = 22
x = 11
45/56
5/7 divided 8/9
5/7 times 9/8
45/56
