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
From my understanding the question is basically asking u to label each Dash/tick mark on the line. They have already given u 0 as the first one, 24 as the fifth one and 60 as the eleventh one. I’m assuming u can use any method.
Answer: use any method of division or skip counting then you will see that each line increases by 6
First line: 0
Second line: 6
Third line: 12
Fourth line: 18
Fifth line: 24
Sixth line: 30
Seventh line: 36
Eight line: 42
Ninth line: 48
Tenth line: 54
Eleventh line: 60
Answer:
b
Step-by-step explanation:
16x² + 8x + 32
8(2x²) + 8(x) + 8(4)
8(2x² + x + 4)
Answer: A 2 1/4
Step-by-step explanation:
9/4 is equal to 2 1/4
9 / 4 = 2.25
2.25 = 2 1/4
