Answer:
PartA
P = 4a
Part B
60 = P fence + 2a
60 = 6a
Part C
40
Step-by-step explanation:
We are building a fence so we are finding perimeter.
Adding the 3 sides
P = a+b+a
P = 2a+b
It is twice as long as it is wide
b= 2a
Replace in the equation for perimeter
P = 2a+(2a)
P = 4a
Part B
We know the perimeter is 60 for the entire backyard
The perimeter of the backyard is the fence plus the longer side
60 = P fence + b
Replacing b
60 = P fence + 2a
We know the equation for the perimeter of the fence is
60 = 4a + 2a
Combing like terms
60 = 6a
Part C
Solve for a and b
60 = 6a
Divide each side by 6
60/6 = 6a/6
10 =a
P fence = 4a
P = 4(10) = 40
Answer:
∠1 = 51° ∠2 = 39°
Step-by-step explanation:
ok since the picture is a right angle put it equal to 90
like this:
3x + x + 22 =90
4x + 22 = 90
4x = 68
x = 17
now we plug it in:
3(17)= 51°
(17) + 22 = 39°
*a straight line is equal to 180, a right angle is 90
does that make sense?
I think what you are looking for is the equation on how this could be displayed.
The baseline is 4, and the hourly rate of r.
This can be shown by:
4 + r = cost
Answer:
All three functions have the same minimum
Step-by-step explanation:
Well radius is always the half it... so 6
