d or b or something
Step-by-step explanation:
He should buy 3 toys because 8x3=24 and 6x4=24
he can buy 3 toys and get 4 packs of batteries and he will have the exact amount.
2.5 hours, because 10 miles an hour times 2 = 20 plus half the time? 2.5
To find the answer for A you add up the interest rate for 2 years which is 16% then find 16% of $9,000 which is $1,440 and that's his interest rate he will have to pay for 2 years. If you want to know how much he has to pay in total for 2 years you simply just add the interest rate $1,440to $9,000 and you get $10,440.
To find the answer for B you add up the interest rate for 6 years which is 48% then find 48% of $9,000 which is $4,320 and that's his interest rate he will have to pay for 6 years. If you want to know how much he has to pay in the total 6 years you simply just add the interest rate $4,320 to $9,000 and you get $13,320.
I hope that helped you.
The distance covered by an object is governed by the expression x³+3x²+2x. The speed equation is given by speed = distance/time. The distance is x³+3x²+2x and the time is x + 1. So, divide them and you will get a speed of x² + 2x
