Answer:

The answer to your question is the letter B. 5y³ - 18y² + 29y - 12  

Step-by-step explanation:

Data

           (y² - 3y + 4)(5y - 3)

Process

1.- Multiply the first terms by 5y

           (y² - 3y + 4)(5y) = 5y³ - 15y² + 20y

2.- Multiply the first terms by -3

            (y² - 3y + 4)(- 3) = -3y² + 9y - 12

3.- Simplify like terms

            5y³ - 15y² + 20y  -3y² + 9y - 12 = 5y³ + (-15y² - 3y²) + (20y + 9y) -12

4.- Result

                                                                = 5y³ - 18y² + 29y - 12

PLEASE MATH HELP DESPERATE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! WILL DO ANYTHING PLEASE. WILL GIVE BRAINLIEST!!!!!!!!!!!!!!!!!

The midpoint is the average of the endpoint coords.
If (x,y) is F, then -6=(-14+x)/2 and 7=(13+y)/2.
-14+x=-12 so x=2, and 14=13+y, so y=1 and F is (2,1).
so the answer is (2,1)

Answer:

(y+1)

Step-by-step explanation:

use quadratic formula.

you will get two values of y

y= 7/5 and y= -1

u can create factors using these values of y (making 0 subject)

like

for 7/5

7/5=y

7=5y

5y-7=0

zero becomes subject in such cases bcz there are no numbers left on that side

now for -1

-1=y

y+1=0

so your factors are 5y-7 and y+1
