Replace all variables with their equivalents.

The expression u + xy now becomes 2 + (9)(6).

Do the order of operations.

2 + (9)(6)
2 + 54
56

So, the answer is 56.

1) Mr. Bond can harvest 2 1/3 acres of corn in 1

creativ13 [48]

This is a fairly simple problem to do. Since you already know how many acres of corn can be harvested in a day then just multiply 10.5 (because of that being however many days being harvested) by 2 1/3. 10.5*2 1/3=24.5. Mr. Bond can harvest 24.5 or 24 1/2 acres of corn in 10.5 days.

If the length of a rectangle is 6 more than twice the width and the total perimeter is 84cm, what is the rectangle's length?

tino4ka555 [31]

Step-by-step explanation:

length = 2×width + 6

84 = 2×length + 2×width

now using the first in the second equation :

84 = 2×(2×width + 6) + 2×width = 4×width + 12 + 2×width

84 = 6×width + 12

72 = 6×width

width = 12 cm

length = 2×width + 6 = 2×12 + 6 = 24 + 6 = 30 cm
