Hello,
2(l+w)=78
Divided 2 from both side
2(l+w)/2=78/2
l+w=39 feet
l=6w+4
Replace l with 6w+4
6w+4+w=39
7w+4=39
Subtract 4 from both side
7w=35
Divided 7 from both side
w=5 feet
l=6w+4
l=6(5)+4
l=30+4
l=34 feet. As a result, the length of the rectangle is 34 feet and the width of rectangle is 5 feet. Hope it help!
Answer:
Step-by-step explanation:
It is not a function
The 4 in the domain is used more than once
Everyday the number is tripled by 3 and x represents the number of days, which we don’t know, so it would be 3x.
He started with 24.
So the equation is:
24+(3x)
A=pi(radius)^2
Radius=Diameter/2
Radius= 14/2=7yds
A=3.14(7)^2
A=153.86yds
Length=3*width
area=12
3W*W=12
w^2=4
w=2
l=6
perimeter=2(l+w)
=2(2+6)
=16
