The expression (-4x + 9)^2 cannot be equal to (-4x)^2 + 9^2 because it is actually equal to the product of two factors (3 + 2sqrt x) (3- 2 sqrt x). One cannot use obviously distributive property. Hence the answer to this problem should be C. as she did not understand both perfect square trinomial and did not determine the product
Answer:
B
Step-by-step explanation:
If it cost $2.05 for each hamburger that's going to be your constant.
And it says plus an additional $2,000 so you will add that after 2.05x.
And it says 13,025 is the total so that would be on the left.
13,025 = 2.05x + 2,000
I'm 100% sure
I took Honors Algebra 1 in 8th grade, so you can trust me!!!
Answer: 18 1/5 + 22 2/5 + 40 1/5
Step-by-step explanation:
To get equivalent expression we need to remove the parenthesis multiply negative sign inside the parenthesis when we multiply negative and negative it becomes positive. So the expression becomes 18 1/5 + 22 2/5 + 40 1/5
C I think (sorry if I’m wrong)
Just in advance ,not very good at it
