Answer:

60 nickels

70 dimes

Step-by-step explanation:

convert $10 to cents

$10 = 1000 pennies

1000 = 5x + 10 (x+10)

1000 = 15x + 100

900 = 15x

x = 60

60 nickels

70 dimes

check to be sure this adds up to $10

ella [17]

Answer:

1: x = -1

2: x = 3

3: x = -3

Step-by-step explanation:

f(x)=<u>x^3+x^2</u>−9x−9

f(x)=x^2<u>(</u>x+1) <u>−9x−9</u>

f(x) = x^2<u>(x+1)</u> - 9<u>(x+1)</u>

f(x)= (x+1)<u>(x^2-9)</u>

f(x) =(x+1)(x-3)(x+3)
