If c (x) = 4x – 2 and d(x) = x2 + 5x, what is (cd) (x)

Mathematics

jolli1 [7]3 years ago

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.

The measure of angle 1 is (3x + 10)° and the measure of angle 4 is (4x – 15)°. Vertical and parallel lines c, d, and e are cut b
Nikitich [7]

Answer:

95 degrees

Step-by-step explanation:

since angles 1 and 4 are vertical angles, they are congruent

3x+10=4x-15

3x-4x=-15-10

-x=-25

x=25

x=25 degrees

angles 4 and 7 are supplementary due to them being alternate exterior angles

lets find the measure of angle 4:

4x-15

4*25-15

100-15

85 degrees

Now, lets find the angle measure of angle 7:

85+x=180

x=180-85

x=95

So, the angle measure of angle 7 is 95 degrees

BigorU [14]

Answer:

2 cakes with the sugar she has and there will still be some sugar left.

Step-by-step explanation:

Amount of sugar in the cabinet of Cassie = 1/2 pound

Amount of sugar required by Cassie to make her cake recipe = 2/10 pound

                                                                                                  = 1/5 pounds

Then

The number of cakes that Cassie can make = (1/2)/(1/5)

                                                                       = 5/2

                                                                       = 2 1/2
