Answer:
Step-by-step explanation:
You can set this up by reversing it.
(9+4)- (x/2)
(13)-(x/2)
(13)-(2x)
=11x
Answer:c
Step-by-step explanation:
Add 44 to both sides and divide by 5 (on both sides) then apply the square root
Same-side interior angles where a transversal crosses parallel lines are supplementary:
The solutions to these equations can probably be done in your head:
- y = 180/(6+4) = 18
- x = (180-90)/5 = 18
The angles at the bottom of the figure, shown as different, are actually the same: 90°.
The angles at the top of the figure, shown as the same, are actually different: 108° on the left, 72° on the right.
Answer:
(x -25)(x+4)
Step-by-step explanation:
x²-21x -100
x²-25x+4x-100
x(x-25)+4(x-25)
(x+4)(x-25).
The correct answer is $7.84
