Answer:
as i see from the picture, this lecture mainly taught you relationship of the angles in a specific condition
such as
corresponding angles, AB//CD ,
alternate angles, AB//CD ,
interior angles, AB//CD
In my figure, a+b is always equal to 180degree if the X line is straight
a+b=180
imagine there is Y line which is parallel to the X line
c+d=180
a=c, b=d because y line and x line is parallel (corresponding angles,X//Y)
then b+a=180, substitute c as a, b+c=180(interior angles, X//Y)
Answer:
16x² + 64x + 64
Step-by-step explanation:
Given
A = 16x²
Increasing the sides by 2, substitute x = x + 2 into A
A = 16(x + 2)² ← expand factor using FOIL
= 16(x² + 4x + 4 ) ← distribute
= 16x² + 64x + 64
If you really want to figure this out you make an equation to solve for the time
let's let
x = time from Elena to Jada and
x = time from Jada to Elena
12 then the equation
12 = 5x +3x
would help figuring out their distance say for one of them
12 = x(5+3)
12/8 = x
1.5 = x
