Answer:
(-3x²- 9x+5) - (-2x²-4x +7)
= (-3x²- 9x²+5) (2x²+4x +7)
=-3x²-9x+5+2x²+4x-7
=-3x²+2x²-9x+4x+5-7
=-x²-5x-2
The answer:
it would take 9 years for the account to grow to $12,700
the steps:
10,000 x .03 = 300
2,700 divided by 300 is 9
y=3x+6
Step-by-step explanation:
point 1 (2;12)
point 2 (4;18)



m=3
y=mx+b
sub in a point and gradient
12=3(2)+b
12=6+b
b=6
y=3x+6
Point g because it’s in the middle.
midpoint= the middle.
20 √2
It would be a 45 45 90 triangle. So both sides are X (20) and the missing side is X √2 (20 √2).
