Let's find the formula for a rectangle:
2L+2W= 90
Now we know the length is equal to 6 more than 2 times the width, let's make the equation.
L=2w+6
Let's plug that in for L in the first equation.
2(2w+6)+2w=90
4w+12+2w
6w+12=90
6w=78
78÷6=13=w
The width is 13, but we need the length. We know the length is equal to 6 more than 2 times the width.
13×2= 26+6= 32
So, the length of the rectangle is 32 ft.
Answer:
Step-by-step explanation:
Por aspa simple:
x²+x-30=0
X +6
X -5
(x+6)(x-5)=0
x+6=0
x=-6
x-5=0
x=5

Answer:
Part a)
Part b)
Step-by-step explanation:
Part a) we have
Solve for n
Subtract 3 both sides
take log both sides
----> using a calculator
Part b) we have
Solve for n
Adds 5 both sides
take log both sides
----> using a calculator
There are 3 feet in a yard, so I would divide 102 by 3, and that is 34
A cheetahs can run 34 yards per minute
Answer:
Yes, the graph represents a proportional relationship. No, the graph does not represent a proportional relationship. It is a straight line, but it does not intersect the point (0, 0).
