Rocky thinks of an odd integer adds the next two consecutive integer which of these could be the sum
tekilochka [14]

Answer:

C

Step-by-step explanation:

1. Let x be the odd integer. Let y be the sum.

x + (x + 1) + (x + 2) = y

3x + 3 = y

Adding two consecutive integers to an odd integer will result in an even integer.

So, you can eliminate choices B and D since they are odd.

Lastly, plug in choices A and C for y and choose the answer that makes x an integer.

Choice C would give you the correct result.

3x + 3 = 44562

3x = 44559

x = 14853

The perimeter of a rectangular park is 200 feet. The length of the park is 40 feet longer than the width.Find the length of the
Leto [7]

\green{ \boxed{\sf \: length \:  \:  = 70 \:  \: feet}}

Step-by-step explanation:

Let assume that,

  • Wide = x

So,

  • length = x + 40

Given,

perimeter = 200 feet

We know that,

Perimeter = 2(length + wide)

So,

200 = 2(x + 40 + x) \\  =  >  \frac{200}{2}  = 2x + 40 \\  =  > 2x + 40 = 100 \\  =  > 2x = 100 - 40 = 60 \\  =  > x =  \frac{60}{2}  \\  =  > x = 30 \: feet

So length = x + 40 = 30 + 40 = 70 feet
