7 is length and 5 is width. Hope this helped!!
The simplest expression is (2w)+(2*3w), because to calculate perimeter, you have to use this formula: 2length+2width.
I believe the answer is :
15x + 40
If you just distribute
Answer:
X= 67
Y= 121
Z= 80
Step-by-step explanation:
To find Y:
(y-9) and 112 are congruent so
y-9=112
y=121
To find Z: (consecutive)
180=121+z+3
180=124+z (combine like terms)
subtract 124 to cancel and move to other side of equation
z= 80
To find X: (consecutive)
180=112+x+1
180=113+x (combine like terms)
subtract 113 to cancel out and move to their side of equation
x = 67
