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:
1 is 20 or 10 2 is 2 3 is b 4 is 2
Step-by-step explanation:
Answer:
Depends where the parenthesis are. But if you solve it using PEMDANS it's 1.475.
Step-by-step explanation:
When solving something like this, you use PEMDAS, sometimes known as GEMDAS and solve it in this order.
P/G=Parenthesis
E= Exponents
M= Multiplication
D= Division
A= Addition
S= Subtraction.
So skip P, E, M, and S because there are no parenthesis, exponents, multiplication, or subtraction signs.
So 7/8=0.875. 9/15=0.6, and if you add those you get 1.475
There are no common factors except 1
