The formula for triangle area is b•h/ 1/2. so you would do 12•5=60. then divide that by 2 to get 30
This can be solver by creating a small equation with x being the number and solving for x. The equation would be 8 + 2( x + 3 ) = -6
Solve for x:
8 + 2( x + 3 ) = -6
Distribute the 2
8+ (2x+6)=-6
Subtract 8
2x+6= -14
Add 6
2x= 8
Divide by 2
x=4
So the number you are looking for is 4
I hope this helps!
For this case we have the following function:
What we should do is evaluate the function for the different values of the independent variable.
We have then:
For x = 8:
For x = 1.8:
For x = x + 8:
Answer:
The results of evaluating the function are:
