The area of a soccer field is 7,700 yd2. The width of the field is 70 yd. What is the perimeter of the field?

Answer: Option 'd' is correct.

Step-by-step explanation:

Since we have given that

Distance traveled by Jesse's car = d

Number of gallons used = g

The relation between distance and number of gallons used is given by

We need to find the constant of proportionality in terms of distance traveled per gallon of gas.

So, Constant of proportionality =

Since we have

Hence, Option 'd' is correct.

Answer:

15

Step-by-step explanation:

I took the test and got it right.

Here,

(s-3)²=0

→s-3=0

→s=3

Substituting s=3 in,

(s+3)(s+5)

=(3+3)(3+5)

=(6)(8)

=48

The answer is -17

The negative 7 and positive 7 add up to 0. They are opposites which cancel out. Think of it like being 7 dollars in debt (negative 7) and that debt is fully canceled out by the positive amount of money (positive 7). Put another way, the negative 7 means you go down 7 while the positive 7 means you go up 7.

After the first two terms cancel to 0, the -17 is the only thing left. Adding 0 to any number keeps that number the same.

Final answer:

The sum of (-7) + (+7) + (-17) in mathematics is -17, because a positive and a negative number of the same magnitude cancel each other out.

Explanation:

In the field of mathematics, particularly in arithmetic, a positive number and a negative number can be added together. In this case, you're adding the numbers -7 (negative 7), +7 (positive 7), and -17 (negative 17).
Let's break it down:

• Negative 7 plus positive 7 gives you 0 because a positive and a negative number of the same magnitude cancel each other out.
• Then, add this result (which is 0) to negative 17. The result of this is -17.

So, the sum of (-7) + (+7) + (-17) equals to -17.
