A. Length - 100 ft Width - 50 ft is the measurement of Tony's backyard.
Albert's Perimeter = 2(l+w) = 2(40+20) = 2(60) = 120 ft.
Tony's Perimeter = 120 ft * 2.5 = 300 ft
Tony's length = 40 ft * 2.5 = 100 ft
Tony's widht = 20 ft * 2.5 = 50 ft
To check tony's perimeter:
P = 2(l + w) = 2 (100 + 50) = 2 (150) = 300 ft.
Answer:
<u>Right</u><u> </u><u>option</u><u> </u><u>is</u><u> </u><u>B</u><u>.</u><u> </u>
Step-by-step explanation:

well the formula to reflecting across the x-axis is (x,-y).so the final points are A'(2,-2) B'(3,-7) C(5,-5) ANSWER
additional information
By the way the -y in the formula does not mean every number will always be negative it means switch the sign so if the point is (5,-7) than reflecting across the x-axis it would be (5,7)
Answer:
r = 7 q - 34
Step-by-step explanation:
Solve for r:
-34 + 7 q - r = 0
Subtract 7 q - 34 from both sides:
-r = 34 - 7 q
Multiply both sides by -1:
Answer: r = 7 q - 34
