Answer:
= 10
Step-by-step explanation:
÷ ![3](https://tex.z-dn.net/?f=3)
if, r = 7 and s = 2
SO..
÷ ![3](https://tex.z-dn.net/?f=3)
..
Add 2 and 1 to get 3.
![7 + \frac{3^{2} }{3}](https://tex.z-dn.net/?f=7%20%2B%20%5Cfrac%7B3%5E%7B2%7D%20%7D%7B3%7D)
Calculate 3 to the power of 2 and get 9.
![7 + \frac{9}{3}](https://tex.z-dn.net/?f=7%20%2B%20%5Cfrac%7B9%7D%7B3%7D)
Divide 9 by 3 to get 3.
7 + 3 = 10
Answer: 55 miles per hour
Explanation: that hint is really useful
So if distance = velocity x time
That means 220 = v x 4 hours
To find v, divided 220 by 4
220 divided by 4 = 55
But I have a question:
Is he driving at a constant speed?
and is this 6th grade math? I’m in that grade but you can trust my answer
If im wrong, someone pls correct me
If im right, mark me brainliest pls, im broke, i have no points-
Goodluck!
Consider the expression below.
(- 6)(x+ 2)
For (x - 6)(x + 2) to equal ,either (X - 6) or (x+2) must equal____
The values of x that would result in the given expression being equal to 0, in order from least to greatest
Answer:
The answer is ![6x^{3} +39x^{2}+54x](https://tex.z-dn.net/?f=6x%5E%7B3%7D%20%2B39x%5E%7B2%7D%2B54x)
Step-by-step explanation:
Volume of the rectangular prism = Length * Width * Height
Length (l) = ![x+2](https://tex.z-dn.net/?f=x%2B2)
Width (w) = ![3x](https://tex.z-dn.net/?f=3x)
Height (h) = ![2x+9](https://tex.z-dn.net/?f=2x%2B9)
By substituting these values to the equation above,
Volume of the rectangular prism = ![(x+2)*3x*(2x+9)](https://tex.z-dn.net/?f=%28x%2B2%29%2A3x%2A%282x%2B9%29)
=![(3x^{2} +6x)*(2x+9)](https://tex.z-dn.net/?f=%283x%5E%7B2%7D%20%2B6x%29%2A%282x%2B9%29)
=![6x^{3} +27x^{2} +12x^{2} +54x](https://tex.z-dn.net/?f=6x%5E%7B3%7D%20%2B27x%5E%7B2%7D%20%2B12x%5E%7B2%7D%20%2B54x)
=![6x^{3} +39x^{2}+54x](https://tex.z-dn.net/?f=6x%5E%7B3%7D%20%2B39x%5E%7B2%7D%2B54x)
Therefore,
The answer is ![6x^{3} +39x^{2}+54x](https://tex.z-dn.net/?f=6x%5E%7B3%7D%20%2B39x%5E%7B2%7D%2B54x)
The answer is 8 because if you divide 52 by 4 it gives 13, do the same to the top and you get 8
