Answer:
it has to be 60
Step-by-step explanation:
4 x 15 = 60
L=w+2 and 2w+2l=44
substitute equation for length in perimeter equation
2w+2(w+2)=44
2w+2w+4=44
4w+4=44
4w=40
w=10
substitute width into length equation to get length
l=10+2
l=12
a=lw
a=12*10
a=120 cm^2
Answer:
7.595
Step-by-step explanation:
Use PEMDAS
So if we know we need to use the parenthesis first since P stands for parenthesis
So solve (0.25 x 4.1) first.
(0.25 x 4.1) =1.025
We know that (0.25 x 4.1) =1.025 so we plug in 8.62-1.025
When subtracted we get the answer of 7.595
5/9-3/8+(-1/4)+1 4/9+1 5/8=3
The mean is every number added, then divided by the amount of numbers. range is the number that occurred most often. What does that get you?
