Answer:
A) -8x^2 - 26x - 15
Step-by-step explanation:
(4x + 3)(-2x - 5)
FOIL
first: 4x*-2x = -8x^2
outer : -5*4x = -20x
inner: -2x*3 = -6x
last: -5*3 = -15
Add these together
-8x^2 -20x-6x -15
-8x^2 -26x-15
Simple interest:
Final value = principle (starting balance) x interest x time in years
Fv = PiN
18,000 x 0.045 x 3 = $2430
2430 + 18000 = $20430
The rate of change=250-125/2-1
=125
the initial value is 700
1.75 kg + 1.54 kg = 3.29 kg or 7.253208 pounds.
