Answer:
(x-y)(x-y)(x-y)= x²-yx+x²-yx-yx+y²-yx+y²
2x²-4yx+2y²
(y-x)(y-x)= y²-yx-yx+x²
y²-2yx+x²
-(y²-2yx+x²) = -y²+2yx-x²
2x²-4yx+2y²-y²+2yx-x²= x²-2yx+y²
or
(x−y−1)(x−y)² ≡ x³−x²+3xy²+2xy−y³−y²−3yx³
Answer:
145 ft
Step-by-step explanation:
According to Cedar Pt web site, the height of the Millennium Force=310'
the Mantis is 165 feet shorter than the Millennium Force
the height of the Mantis=310-165=145'
here ' means feet
Answer:
2x-y=7
Step-by-step explanation:
y-5=2(x-6)
y-5=2x-12
2x-y-12=-5
2x-y=-5+12
2x-y=7
Lets suppose his initial weight was 60 kilograms
A gain of 20% would make his new eight 60 + 20*60/100
= 60 + 12
= 72 kg
he lost 25% of this:-
= 72 - 25 * 72/100 = 54 kg
This = (54/60) * 100 = 90% of his beginning weight Answer
17 x 0.52= 8.84
Hope This Helps
