MariettaO [177]2 years ago
6 0

Answer:

First option

Step-by-step explanation:

The result of first expression:

7(6+z) multiply 7 with inside the parenthesis

7(6+z) = 42 + 7z

the result of second expression:

since we need to do multiplying first,

7*6 = 42 and 7*z = 7z

then we add them

42 + 7z this is the same result we found for the first equation

I need Help with 9??
andreyandreev [35.5K]
Sometimes it helps to draw it...so u can see

       7                   7
J_______K_________L
|__________________|
           4x - 2

since K is the midpoint, it splits the segment in 2 equal parts
JK + KL = JL
7 + 7 = 4x - 2
14 = 4x - 2
14 + 2 = 4x
16 = 4x
16/4 = x
4 = x <====

KL = 7 <===
JL = 4x - 2....4(4) - 2.....16 - 2 = 14 <==
