Step-by-step explanation:
EQUATION: Volume=length x width x height.
V=l×w×h
1620cm^3=9cm×9cm×xcm
1620cm^3=81cm^2 ×xcm
xcm= 1620cm^3/81cm^2
xcm= 20cm
Answer:
Yes
Step-by-step explanation:
In order to make a triangle with non-zero area, the sum of the shorter two sides must be greater than the longest side.
Here, 4 + 4 > 7, so the lengths can form a triangle.
Answer:
no because 2(6-3x)+x equals 12-5x and 2(3x)+x equals 7x

Hello! To solve this equation, let's set it up like this: 75 + 20m = 35m. This is because Company B does not charge an upfront fee, so all you have to do is 35m and Company A charges $75 upfront and then $20 per month, so you do 75 + 20m. First, you subtract 20m from both sides. When you do, you get 75 = 15m. Now, you divide each side by 15 to isolate the m. When you do that, you get 5. Let's plug in the numbers to see what we get. 20 * 5 is 100 + 75 = 175. 35 * 5 =175. 175 = 175. There. The two companies will charge the same amount in 5 months. m = 5.
You could just put 0 for a and b.
It would work.
