Answer:
v=−5
Step-by-step explanation:
2v + 18 = 16 - 4(v + 7)
2v+18=16−4(v+7)
2v+18=16+(−4)(v)+(−4)(7)(Distribute)
2v+18=16+−4v+−28
2v+18=(−4v)+(16+−28)(Combine Like Terms)
2v+18=−4v+−12
2v+18=−4v−12
Add 4v to both sides.
2v+18+4v=−4v−12+4v
6v+18=−12
Subtract 18 from both sides.
6v+18−18=−12−18
6v=−30
Divide both sides by 6.
6v
/6
=
−30
/6
v=−5
Step-by-step explanation:
GI = GI (common)
GJ=HI(given)
GH = JI(given)
so triangle GJL and triangle GHI are congruent by S.S.S axiom,
<J=<H (corresponding angle of congruent triangles are equal)

Answer: 3n-1
The difference between each of the numbers is 3. This means that we have 3n.
If we assume that for the first number n=1, then 3*1=3, but the value we have is 2. This means that we must subtract 1 to get from 3 to 2.
