When you have something like this, all you need to do is substitute the values, the last is for what value of x
For the first one;
((x^2+1)+(x-2))(2)
(x^2+x-1)(2)
(2)^2+(2)-1
4+2-1
5
For the second one;
((x^2+1)-(x-2))(3)
(x^2-x+3)(3)
(3)^2-(3)+3
9-3+3
9
For the last one;
3(x^2+1)(7)+2(x-2)(3)
3((7)^2+7)+2((3)-2)
3(49+7)+2(3-2)
3(56)+2(1)
168+2
170
The distributive property
Answer:
$0.32/ounce
Step-by-step explanation:

Answer:
-7
Step-by-step explanation:
Hey there! :D
The midpoint and the outside line are symmetrical to eachother, 2(BF)= AE
Two midpoint segments equals one AE segment.
So, use the representation above and plug in the numbers.
2(23)= 5x -4
56= 5x-4
Add 4 to both sides.
60=5x
Divide by the 5.
x=12
I hope this helps!
