Answer:
x=70
Step-by-step explanation:
x/10=7
First you need to get the x by itself, so you should do the opposite of what is happening to the x.
In this case the x is being divided so you would need to multiply.
So multiply the x by 10 and this gets it by itself.
But you have to do to one side what you do to the other.
So multiply the other side by 10 as well!
This equals x=70
To show work on both sides, show the multiplication of both sides by 10
6x17=100 so you basically multiply 6x17 which would be 100
2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)

a= 1/2 b x h
= 5cm x 72cm
= 360cm
