<span>–9x(5 – 2x)
= -45x + 18x^2
= 18x^2 - 45x
answer
</span>18x^2 - 45x
Answer:
A.
Step-by-step explanation:
6^(1-1) + 6^(2-1) + 6^(3-1) + 6^(4-1)
= 1 + 6 + 36 + 216
= 259.
Y = 4/5x + 30
4/5 because the slope is 4 up, 5 right. 30 is the y-int
Answer:


The equations have the same slope but different y-intercepts. This means the lines are parallel and there is no solution (since they do not intersect).
