a is 41

b is 37

c is 63

solving the equation will give you the value of x°

Answer:

-4(-7/30)-3/5=1/3

4(-1/15)+3/5=1/3

Step-by-step explanation:

1. -4x-3/5=1/3

-4x=1/3+3/5

-4x=14/15 <- divide both sides

x= -7/30

2. 4x+3/5=1/3

4x=1/3-3/5

4x= -4/15 <-divide both sides

x= -1/15

Directions:Use the product rule to simplify the following monomials.

nadezda [96]

Answer: $-12m^3n^3$

Step-by-step explanation:

$\frac{1}{4}\left(8mn\right)\left(-6m^2n^2\right)$

$=-\frac{1}{4}\cdot \:8mn\cdot \:6m^2n^2$

$=-\frac{1}{4}\cdot \:48mnm^2n^2$

$=-\frac{1}{4}\cdot \:48m^3nn^2$

$-\frac{1}{4}\cdot \:48m^3n^3$

$=-12m^3n^3$

What is the value of a in the polynomial

Alexandra [31]

Answer: a= 16

Step-by-step explanation:

We have the following expression:

$(y-4)(y^2 +4y +16)$

To find the value of the coefficient "a" you must use the distributive property to multiply the expression:

$(y-4)(y^2 +4y +16)$

until you transform it to the form:

$y^3 +4y^2 +ay -4y^2 -ay-64$

Then we have

$(y-4)(y^2 +4y +16)\\\\(y^3 +4y^2 +16y -4y^2 -16y-64)\\\\$

Therefore the value of a in the polynomial is 16
