Simplify 6x + 3(–2x + 7) + 2x.
a.
2x + 21
b.
14x + 21
c.
–10x + 7
d.
–14x + 7

answer: 21 + 2 x

step-by-step explanation:

simplify the expression.

simplify 6x + 3(–2x + 7) + 2x.

a.2x + 21

let's simplify step-by-step.

6x+3(−2x+7)+2x

distribute:

=6x+(3)(−2x)+(3)(7)+2x

=6x+−6x+21+2x

combine like terms:

=6x+−6x+21+2x

=(6x+−6x+2x)+(21)

=2x+21

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
