5(3x-6) is equivalent to 15x - 30 if they are equivalent if the two values are the same.
<h3>What is expression?</h3>
An expression is a set of terms combined using the operations +, – , x or , /.
Given expression:
5(3x-6) is equivalent to 15x - 30.
If we put x=2 in both expression, we get finite value.
To check both the expression are equal or not we have to solve by putting the value.
So,
They are equivalent if the two values are the same otherwise not.

L=3w-4
Perimeter = 64
64=2L+2w
Plug in L that we solved above into this equation:
64=2(3w-4)+2w
64=6w-8+2w
64=8w-8
72=8w
w=9
Plug W back into the equation above to solve for L
L=3w-4
L=(3)(9)-4
L=23
Check the answer with the perimeter formula:
P=2L+2w
P=2(23)+2(9)
P=46+18
P=64
Answer:
Let there were total x people at the conference
so 32%of x is 216
32/100×x=216
x=216×100/32
x=675
So total people present at the conference were 675
Answer:
w = 9 ft
l = 13 ft
Step-by-step explanation:
2w + 2(w+4) = 44
simplify:
4w + 8 = 44
4w = 36
w = 9 ft
l = 13 ft
