A football field is a rectangle where the length is 100 yards. If the total perimeter is 1040 feet, what is the
AleksandrR [38]

Answer:

Step-by-step explanation:

The width is 220 feet.

100 yards = 300 feet

300 x 2 = 600

1040-600 = 440

Since you have 2 equal sides representing the width 440/2 = 220

Check it by adding all sides to get perimeter:

220+220+300+300= 1040

Use the distributive property to find an expression equivalent to 24 + 64.
LUCKY_DIMON [66]

Answer:

8(3+8)

Step-by-step explanation:

The distributive property of multiplication states that

A(B+C) = A* B + A* C

Here, we can say that

8(3+8) = 8*3 + 8* 8 = 24 + 64. This seems correc,t but we can check the other options to make sure

6(4 + 8) = 6 * 4 + 6*8 = 24 + 48. This is incorrect

24 + (8)(8) . The 24 and 8 are not in the same parenthesis, so we cannot multiply them. Using PEMDAS, we multiply first, so 24+(8)(8) = 24 + 8*8 = 24 + 64. If there are multiple solutions, this can work. If not, this does not use the distributive property as we are not adding anything in the parenthesis.

Similarly, for (2)(12) + (8)(8), we are not adding anything in the parenthesis, but we can use PEMDAS to get 2*12 + 8*8 = 24 + 64, so this would also work but does not use the distributive property.
