When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed)
Answer:
The length of the base is 
Step-by-step explanation:
Since we know the formula to find the area of a triangle is
, we can plug in and solve for b. When we plug into the formula we get:
= 
First multiply by 2 on both sides to get rid of the 1/2 on the left. After doing this we get:

Then we can multiply by 5 on both sides to get rid of the 1/5 on the left. After doing this we get out answer:

Answer:
Simplify 2(x+1)\times 22(x+1)×2 to 4(x+1)4(x+1).
4(x+1)=324(x+1)=32
2 Divide both sides by 44.
x+1=\frac{32}{4}x+1=
4
32
3 Simplify \frac{32}{4}
4
32
to 88.
x+1=8x+1=8
4 Subtract 11 from both sides.
x=8-1x=8−1
