Longitud = L Ancho = A
2A + 2L = 54
L = 2A Sustituir este valor por L en la primera ecuación:
2A + 2(2A) = 54
2A + 4A = 54
6A = 54
A = 9
También porque L = 2A,
L = 2(9) = 18
Option A. is correct for the given condition.
Lets solve it through steps of range and functions,
First of all, Solve the equation:
(1)
(2)
So these would be the ranges of X in between 5 and -5.
Hence option A.

Let, the number of toy trucks = x
Then, number of toy cars = (x + 12)
Now, we have: x + x+12 = 38
2x + 12 = 38
2x = 38 - 12
2x = 26
x = 26/2
x = 13
So, there are 13 toy trucks in total.

Answer:
36 cm
Step-by-step explanation:
P = 2l + 2w
Plug in
P = 2(14) + 2 (4)
P = 28 + 8
P = 36
Answer:233.333%
Step-by-step explanation:
1. 10-3=7 subtract end by start
2.7/3=2.333 divide difference by absolute value of start
32.333x100=233.333% multiply by 100 if negative its decreasing if positive it increasing
