Identify the expression equivalent to 2x + 8 by substituting x = 7 and x = 5.
A.
2x + 10 + 10
B.
2(x + 2)
C.
(x + 4) + (x + 4)
D.
(x+4)
E.
212x + 4)

the answer is C ;P

Step-by-step explanation:

C is the answer because the expression pulled apart is just an addition problem between two parenthesis. I hope this helps!

Step-by-step explanation:

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
