Answer:

Hey there!

The perimeter of the flower bed is 2\sqrt{24} +2\sqrt{54} meters.

This can be simplified, however (shown below)

2\sqrt{4(6)}+2\sqrt{9(6)}

4\sqrt{6}+6\sqrt{6}

10\sqrt{6}

The perimeter is 10\sqrt{6}

Let me know if this helps :)

The sale price of every item in a store is 85% of its usual price.
Vladimir [108]

Answer

a. The backpack is $4.50

b. The sweatshirt is $2.70

Step-by-step explanation:

a. 30 x 0.15 = 4.50 (The 0.15 is from the price you are actually paying for the item. Because the item is 85% off, you are paying for 15% of the usual price. 15% as a decimal is 0.15 so you multiply that to the original price to find the amount u will pay.)

b. 18 x 0.15 = 2.70
