Answer:
x2(y2 - 1) Now by using the identity a2 - b2. x2(y2 - 12) = x2(y + 1) (y - 1) Also, factorizing xy2 - 2xy - 3x by taking the common factor 'x' we get, x(y2 - 2y -
Step-by-step explanation:
Answer:
Roses= $8.4
Daises= $15.6
Step-by-step explanation:
Let represent the daises and let r represent d roses
r + d= 24....equation 1
0.25r + 0.90d= 16.40.......equation 2
r= 25-d
Substitute 25-d for r in equation 2
0.25(25-d) + 0.90d= 16.40
6.25-0.25d+0.90d= 16.40
6.25+0.65d= 16.40
0.65d= 16.40-6.25
0.65d= 10.15
d= 10.15/0.65
d = 15.6
Sub 15.6 for d in equation 1
r+d= 24
r+15.6= 24
r= 24-15.6
= 8.4
Price of daises is $15.6
Roses is $8.4
His current quiz score would be 60
7 + 2x = 10
subtract 7 from both sides: 2x = 3
divide by 2: x = 1.5
x = 1.5
The answer would be an=-2+5n
