To determine the expression that is equivalent to 8a + 20, all you have to do is find the common denominator and divide the values by it.
8a + 20
8a/4 + 20/4
4(2a + 5).
The correct solution would cue the second option - 4(2a + 5).
Answer:144
Step-by-step explanation:v=l•w•h
Length= 12cm
Width=2cm
Height=6cm
Multiply them to get the volume.
V=144
Answer:
182.414
Step-by-step explanation:
We have 182 ones which we put before the decimal point. After the decimal point the place values are tens hundredths and thousands.
The first answer is definately C.y=-3x+7 and i AM UNABLE TO COMPLETE the next one being no figure is shown.PLEASE MARK BRAINLIEST!!!
Answer:
For the table on the left the rate of change is ![22.8](https://tex.z-dn.net/?f=22.8)
For the table on the left the rate of change is ![-2](https://tex.z-dn.net/?f=-2)
Step-by-step explanation:
The range of change is the slope. The slope can be found with the following formula:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
<u>For the table on the left</u>
Choose two points. In this case you can choose (-1,-24), (4,90)
You can say that:
![y_2=-24\\y_1=90\\\\x_2=-1\\x_1=4](https://tex.z-dn.net/?f=y_2%3D-24%5C%5Cy_1%3D90%5C%5C%5C%5Cx_2%3D-1%5C%5Cx_1%3D4)
Substituting these values into the formula, you get:
![m=\frac{-24-90}{-1-4}\\\\m=22.8](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-24-90%7D%7B-1-4%7D%5C%5C%5C%5Cm%3D22.8)
<u>For the table on the right</u>
Choose two points. You can choose (3,-6), (-6,12)
You can identify that:
![y_2=-6\\y_1=12\\\\x_2=3\\x_1=-6](https://tex.z-dn.net/?f=y_2%3D-6%5C%5Cy_1%3D12%5C%5C%5C%5Cx_2%3D3%5C%5Cx_1%3D-6)
Substituting these values into the formula, you get:
![m=\frac{-6-12}{3-(-6)}\\\\m=-2](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-6-12%7D%7B3-%28-6%29%7D%5C%5C%5C%5Cm%3D-2)
