Answer:
24x - 4
Step-by-step explanation:
Perimeter of a table = 2(length + width)
length of Christina's table is the product of 4 and X
Length = 4x
The width of her table is 2 less
than twice the length.
Width = 2(4x) - 2
= 8x - 2
Perimeter of a table = 2(length + width)
= 2{4x + (8x - 2)}
= 2(4x + 8x - 2)
= 2(12x - 2)
= 24x - 4
Perimeter of a table = 24x - 4
It’s 120 because 10 times 3 times 4 = 120

p- parentheses
e- exponents
m- multiplication
d- division
a- addition
d- subtraction
so first you do the problems inside the parentheses
4•3=
2•6=
10t
