Answer:
e(x) = d(x)+4
Step-by-step explanation:
d(x) = ( x +2)^2 -4
Add 4 to each side
d(x) +4 = ( x +2)^2 -4+4
d(x) +4 = ( x +2)^2
We know that (x=2)^2 = e(x)
d(x) +4 = e(x)
e(x) = d(x)+4
i can barely see it in the imagine can you spell it for me please
Answer:
EY = 60
DW = 68
DE = 128
Step-by-step explanation:
Given
As YW is the perpendicular bisector of EF, then EY = FY
FY = √(FW² - YW²) = √(68² - 32²) = 60
⇒ EY = 60
As WX is the perpendicular bisector of DF, then DW = FW
As FW = 68, then DW = 68
As WZ is the perpendicular bisector of DE, then DZ = EZ = 64
Therefore, DE = DZ + EZ = 64 + 64 = 128
In algebra, symbols are used to represent numbers. Example: 5x=20 or 4x=24
You reverse the inequality symbol if you divide or multiply by a negative number in order to solve the inequality.
