2) (5 feet)(2 feet) = (5 ft)(2ft) = 5 * 2 * ft * ft = 10 * ft * ft = " 10 ft² " .

I think it might be c, or a.
Answer:
A. 592 - 286 - 49 = c
Step-by-step explanation:
A school sold brownies and cupcakes at a bake sale. There were 592 total items available for sale. All 286 brownies were sold. Of the cupcakes for sale, 49 did not sell. How many cupcakes did sell at the bake sale?
Total number = 592
Total number of brownies = 286
The cup cakes for sale = 592 - 286
= 306 cupcakes.
49 of the cupcakes did not sell
The cupcakes that sold = 306 - 49
= 257 cupcakes were sold.
Therefore, the correct equation to solve. A. 592 - 286 - 49 = c
Answer:
94
Step-by-step explanation:
Surface area of a rectangular prism = 2(lw + wh + lh)
where l = lenght, w = width and h = height
here we are given that the rectangular prism has a lenght of 3, a width of 4 and a height of 5.
So we have SA = 2(lw + wh + lh)
==> plug in l = 3, w = 4 and h = 5
SA = 2((3)(4) + (4)(5) + (3)(5))
==> find products of numbers that are next to each other seperated by parenthesis
SA = 2(12 + 20 + 15)
==> find sum of values in parenthesis
SA = 2(47)
==> multiply 2 and 47
SA = 94
