Answer:

18 in

Step-by-step explanation:

Area of rectangle = 3 times the area of the square

Area of square = a² ; a = side length

a = 12 in

Area of square = 12² = 144 in²

Area of rectangle = 3 * 144 = 432 in²

Length of rectangle = 24 in

Width = x

Area of rectangle = length * width

432 = 24 * x

x = 432 / 24

x = 18 in

Andre has seven dollars he needs $50 to buy a skateboard each week his grandmother pays him four dollars to complete some chores
SVEN [57.7K]

Answer:

$11

$39

Step-by-step explanation:

Amount Andre has = $7

Amount his grandmother pays him every week = $4

Amount Andre needs to buy a skateboard = $50

how much money does Andre have after the week?

Amount of money Andre has after the week = Amount Andre has + Amount his grandmother pays him every week

= $7 + $4

= $11

Amount of money Andre has after the week = $11

Amount Andre needs more to buy the skateboard = Cost of the skateboard - Amount of money Andre has after the week

= $50 - $11

= $39

Amount Andre needs more to buy the skateboard = $39

5^10/5^3 rewrite in the form of 5^n
Sergeeva-Olga [200]

Answer:

5^7

Step-by-step explanation:

To rewrite the expression, you use the laws of exponents.

Using the law of exponents of division, you subtract the exponent of the smaller value (5^3) from the larger value (5^10).

Your expression would now be this:

5^10-3

Since the bases have the same value (5), they remain the same.

As a result of 5^10-3, you would get 5^7 as your answer.

To check that both are equivalent to each other you solve and find the values of both expressions.

5^7=78125

5^10/5^3=78125

5^7=5^10/5^3
