Answer:
2. A = 12ft * 8ft
Step-by-step explanation:
To find the area, multiply the two different side lengths together.
Answer:
I think it is (36-6)+4 because it says 6 less than the quotient of 36 so it is 36-6 and 4 so it becomes +4 and the answer is (36-6)+4
Answer:
4 Hours
Step-by-step explanation:
we will set up two linear equations first by taking the initial height if each candle and subtracting the rate they burn at times our input variable of time (x) equal to height (y)
So, 8-7/10x=y and 6-1/5x=y
then, because both equations equal y you can set them equal to each other so
8-7/10x=6-1/5x
Finally, solve for x
8-7/10x=6-1/5x
subtract 6 from both sides
2-7/10x=-1/5x
add 7/10 x to both sides (1/5x=2/10x)
2=5/10x
simplify
2=1/2x
x=4
It will be 6.75 cm2 because if you multiply 1.5 and 3 you get 6.75
