Answer:
Multiply the first two binomials: (x+2) & (x+4) using the FOIL method (First, Outer, Inner & Last).
(x+2)(x+4) = x^² + 4x + 2x + 8 = x^² + 6x + 8
Then we multiply the trinomial that we got from the first stage and multiply that by the remaining binomial:
(x^² + 6x + 8) (x + 4)
= x^³ + 4x^² + 6x^² + 24x + 8x + 32
Collect the like terms together to give you:
x^³ + 10x^² + 32x + 32
Answer:
Problem 1 = 9
Problem 2 = 260
Step-by-step explanation:
Let A and 4A be the investment amounts.
The total profit is 3480=0.06A+0.20A=0.26A, so Fund A investment, A=3480/0.26=$13384.62, and Fund B is $53538.46.
Answer:
$309.20
Step-by-step explanation:
multiply 35.20 by 4 and subtract it from 450
Answer:
360°
Step-by-step explanation:
It would be the same thing as finding the sum of a rectangle where all 4 angles add up to 360° or think of it as a circle where circles = to 360° (I hope this makes sense)
