Answer:
55
Step-by-step explanation:
JL = JK + KL
84 = 3x+5 + 6x+7
Combine like terms
84 = 9x +12
Subtract 12 from each side
84-12 = 9x+12-12
72 = 9x
Divide by 9
72/9 = 9x/9
8 =x
We want KL
KL = 6x+7
6*8 +7
48+7

Answer:
Step-by-step explanation:
The given equation is 
We want to rearrange this equation so that, n becomes the independent variable.
This means we must solve form, m which becomes the dependent variable.
We expand the parenthesis to get:
We now subtract 1 from both sides to obtain:
We simplify to obtain:
This can be rewritten as
Answer:
x =0 and x = 4
Step-by-step explanation:
It is a quadratic function and hence will have two roots. It cuts graph at 2 points( x - axis ). Hence has two roots.
