c(x) = 4x - 2
d(x) = x^2 + 5x
4x - 2(x^2 + 5x)
<em><u>Using FOIL, distribute each term appropriately. </u></em>
4x^3 + 20x^2 - 2x^2 - 10x
<em><u>Combine like terms.</u></em>
4x^3 + 18x^2 - 10x is the simplified polynomials achieved when c(x) and d(x) are multiplied.
Answer:B-70
Step-by-step explanation:
from the figure, In 


Thus we can write

To find x-intercept, put the Y value = 0;
4x - 2y = -12
-> 4x -2.0 = -12
-> 4x = -12
-> x = -12/4
-> x = -3
X-intercept: (-3,0)
Now do the reverse to find the y-intercept, X = 0;
4x - 2y = -12
-> 4.0 - 2y = -12
-> -2y = -12 x(-1)
-> 2y = 12
-> y = 12/2
-> y = 6
Y-intercept: (0, 6)
Answer:
13 + 3x= 31
Step-by-step explanation:
Call x as the number of months that Marc and Corinna have the same number of book.
45 +4x= 61 +2x
4x- 2x= 61-45
2x= 16
x= 8
