Answer:
108
Step-by-step explanation:
a = b*h
a = 9*12
a= 108m^2
Answer:
D) 43.1
Step-by-step explanation:
What we want to do here is find the total volume of the box in cubic inches, then divide it by the number of apples inside. This will tell us how big one apple is in cubic inches.
Box One:
20×13×12 = 3120
3120÷72 apples = 43.3 inches³
Box Two:
12×12×12 = 1728
1728 ÷ 40 = 43.2 inches³
Box Three:
20×10×6 = 1200
1200÷28 = 42.8 inches³
Take those three numbers and find their mean. Add them up and divide by three. You will get 43.1 inches ³.
ΔABC is a right triangle
By the Pythagorean theorem:
AC = √(BC² - AB²) =√(5²-3²) = √(25-9) = √16 = 4
ΔBED is a right triangle
DE = 4
BE = AB + AE = 3 + 4 = 7
By the Pythagorean theorem:
BD = √(BE² + DE²) =√(7²+4²) = √(49+16) = √65
Answer: BD = √65
Divide -6 by -2. The answer is -3. Add the x. So the answer is -3x.
6:1 is the simplified answer
