Solve for b in the formula 3a+2b =c A.) b=c-3a/2 B.) b= c-2/3a C.) B= 2c/3a D.) b= c-3a

Agata [3.3K]

Answer:

b = (c-3a)/2

Step-by-step explanation:

3a+2b =c

Subtract 3a from each side

3a-3a+2b =c-3a

2b = c -3a

Divide each side by 2

2b/2 = (c-3a)/2

b = (c-3a)/2

Multiply (2x+3) (-x -2)

Marysya12 [62]

Answer:

$-2x^{2} -7x-6$

Step-by-step explanation:

(2x + 3) (-x - 2)

distribute first term, to the second term:

2x(-x) + 2x(-2) + 3(-x) + 3(-2)

multiply:

$(-2x^{2})$ + (-4x) + (-3x) + (-6)

$-2x^{2} -4x-3x-6$

combine the like terms:

$-2x^{2}$ - 4x - 3x - 6

-7x

$-2x^{2}$ - 7x - 6

final answer :

$-2x^{2}$ - 7x - 6

hope this helped !!
