Answer:

49

Step-by-step explanation:

The formula for the whole square is

\left ( a+b \right )^2=a^{2}+2ab+b^{2}

So, to make the complete square, in the expression

x^{2}+14x = - 32

First take half of the term 14 x that is 7x and then divide it by x so it is 7. Now take its square that is 49. So add 49 on both the sides to make the given expression as a whole square.

x^2+14x = (x+7)^2

7^2 = 49

so you would add 49 to both sides

Fifty students in the seventh grade are trying to raise at least $2000 for sports supplies. They already raised $750. How much s
Vaselesa [24]

Answer:

x ≥ 25

Step-by-step explanation:

In the seventh grade, fifty students are trying for sports supplies to raise at least $2000. They already have $750.

Let us assume that each student has to raise $x more to meet the goal.

Then, a total of 50 students will raise $50x more.

Therefore, the inequality to solve for x will be  

750 + 50x ≥ 2000

⇒ 50x ≥ 1250

⇒ x ≥ 25 (Answer)

Give two examples of repeating decimals and their corresponding fractions. Show your work.
n200080 [17]
1/9 = 0.1111111111...
That's a repeating decimal because the 1 repeats over and over again.

1/3 = 0.33333333...
That's a repeating decimal because the 3 repeats over and over again.

Have an awesome day! :)

Which is another way to write this number? (3 x 1,000) + (3 x 10) (3 x 1/100) + (3 x 1/1000)
elena55 [62]
The answer should be 3030.033, since 3*1000 is 3000, 3*10 is 30, 3*1/100 is 0.03, and 3*1/1000 is 0.003.
