So a slope of a line can be perpendicular. So if the slope is a/b then the slope perpendicular to that is -b/a. PLEASE MARK AS BRAINLIEST!!
Answer:
Step-by-step explanation:
Given:
Base length:
A = 8.5 m
B = 4 m
Height, h = 2 ft
1 gallon = 350 ft^2
Area of trapezoid = 1/2 × (A + B) × h
= 1/2 × (8.5 + 4) × 2
= 12.5 ft^2
1 gallon = 350 ft^2
2 gallons = 700 ft^2
1 podium = 12.5 ft^2
= 700/12.5 podium
= 56 podiums will be painted with 2 gallons of paint.
9 because it take 3 to fill 1/3 do 3 times 3 and its nine
Answer:
6c^2-cd-d^2
Step-by-step explanation:
How you get the answer is you use the process called FOIL. The F is front, so you multiply the 2c and the 3c to get 6c^2. The O is the outer, so you multiply the 2c and the d(because they are on the outer sides of the parenthesis) to get 2cd. The I is the inner, so you multiply the -d and the 3c(because they are on the inner sides of the parenthesis) to get -3cd. The L is the last, so you multiply d and -d to get -d^2. The 2cd and the -3cd are the same so you have to minus them to get -cd. So the answer is:
6c^2-cd-d^2.
Answer:
6/3=2/1
Step-by-step explanation:
6/3 is the same as 2/1 because if we divide the common denominator, 3, on both sides, your answer will be 2/1.
