What is the value of x in 34 + 2x = 40

alekssr [168]

Hello from MrBillDoesMath!

Answer:

Discussion:

34 + 2x = 40 => subtract 34 from both sides

(34-34) + 2x = 40 - 34 => as (34-34) = 0 and 40-34 = 6

2x = 6 => divide both sides by 2

x = 6/2 = 3

Check the answer:

Does 34 + 2x = 40 if x = 3 ?

Does 34 + 2(3) = 40 ?

Does 34 + 6 = 40 ? YES! so the answer checks.

Thank you,

MrB

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 !!
