Answer:
16x^2 -8x +1
Step-by-step explanation:
The square of a binomial expands as ...
(a +b)^2 = a^2 +2ab +b^2
So, you need to look for a trinomial with first and last terms that are perfect squares and a middle term that is double the product of the roots of those terms.
This pattern matches ...
16x^2 -8x +1 = (4x -1)^2
Answer:
Options A and C
Step-by-step explanation:
<u>To have a unit rate of change of 4.5 means to have the slope at 4.5</u>
A. y = 62 + 4.5x GOOD
B. c = 4.5 + 3h - 1 WRONG
C. c = 12 + 4.5h - 4.5 GOOD
D. y = 3.5x + 1 WRONG
E. y = 4.5 + 20x WRONG
Answer: Options A and C
2.5 *(10)+15=40
I guess this is the answer :)
