Answer:
Step-by-step explanation:
2x⁴ + 4x³ - 30x² = 2x²*(x² + 2x - 15)
x² + 2x - 15
Sum = 2
Product = -15
Factors = 5 ; (-3)
x² + 2x - 15 = x² + 5x - 3x - 3 *5
= x(x + 5) - 3(x + 5)
= (x + 5)(x - 3)
2x⁴ + 4x³ - 30x² = (2x²) (x + 5)(x - 3)
The answer is 9:16 just add 9+7=16 and then we know out of the 16 nine were dogs so 9:16
(-6,26) are the coordinates of the other endpoint because it it the same distance from the midpoint in the opposite direction of the other endpoint
So perm cost 2 times as hair cut
perm=2 times haircut
she also needs 5 dollars for lunch
so therefor if 95 is enough to cover it we do
cost=lunch+perm+haircut
cost=5+perm+haircut
subsitute
95=5+2 times haircut+1 time haircut
add like terms
95=5 +3 times haircut
subtract 5 from both sides
90=3 times haircut
diide by 3
30=haircut
subsitute
perm=2 times haircut=2 times 30=60
perm=$60
0.2, 0.75, 60%, 1/2, 1, 1 1/4
60% is the same as 60/100 or 0.6
1 1/4 is the same as 5/4 or 1.25
1/2 is the same as 0.5
Now our list is
0.2, 0.75, 0.6, 0.5, 1.25 and 1
So from largest to smallest your answer would be...
1.25 , 1 , 0.75 , 0.6 , 0.5 , 0.2
