(a/b)(c/d)=(ac/bd)
Therefore:
(5/4).(2/5)=(5*2)/(4*5)=10/20=1/2
(3/8).(-1/2)=(3*(-1)) /(8*2)=-3/16
(2/5)(5/2)=(2*5)/(5*2)=10/10)=1
(1/2)(1/3)=1/6
(-1/4)(-2/3)=[(-1)*(-2)] / (4*3)=2/12=1/6
Answer:
1)
32x^2 - 28x - 15
2)
30x^2 + 54x - 12
Step-by-step explanation:
1.
(8x+3)(4x-5)
Using FOIL
= (8x)(4x) + (8x)(-5) + (3)(4x) + (3)(-5)
= 32x^2 - 40x + 12x - 15
= 32x^2 - 28x - 15
2.
(10x-2)(3x+6)
Using FOIL
= (10x)(3x) + (10x)(6) + (-2)(3x) + (-2)(6)
= 30x^2 + 60x - 6x - 12
= 30x^2 + 54x - 12
Answer:
he school collected 235 cans a day
Nicholas had 15 cans at home
Step-by-step explanation:
The school collected 235 cans a day
Nicholas had 15 cans at home
Step-by-step explanation:
Looking at the equation:
15 is a constant, meaning that even at x=0 days, nicholas would have had 15 cans, meaning he already had them at home
235 is the number that the variable(the number of days) is multiplied with, this means that 235 is the number of cans that can be collected daily.

No matter what the indices are just follow the law of indices for division:
xᵃ ÷ xᵇ = xᵃ - ᵇ. Most importantly the base x must be the same.
c² ÷ c³ = c² -³ = c^(-1) = 1/c
