What number "c" completes the square: x^2 - 14x + c

Mathematics
1 answer:
Vladimir79 [104]3 years ago
6 0

Answer:

49

Step-by-step explanation:

To complete the square we use the formula:

c=(\frac{b}{2} )^{2}

So we can plug in 14 for b to find c.

c=(\frac{14}{2} )^{2}\\\\c=(7 )^{2}\\c=49

Now this equation can be factored into:

(x-7)^{2}

What does it mean to eliminate a variable?
uranmaximum [27]

Answer:

The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation.

So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation. And since x + y = 8, you are adding the same value to each side of the first equation.

I=$720, P=$1000, r=9%
UNO [17]
I = PRT

720 = (1,000)(0.09)(t)
720 = 90(t)
720/90 = t
8 = t  or t = 8

I am not sure if it is terms  of months or years but 8 is the answer. hope it helps :)

Arliss has two pieces of carpet runner. One is yards long and the other is yards long. She needs 10 yards of carpet runner altog
Alekssandra [29.7K]
Given:
10 yards required
5 2/3 yards on hand.

We need to subtract the yards on hand from the total yards required.

First, we need to convert the mixed fraction into an improper fraction.

5 2/3 = ((5*3)+2)/3 = (15+2)/3 = 17/3

Second, we need to multiply 10 by a fraction that will give us the denominator of 3.

10 * 3/3 = (10*3)/3 = 30/3

Third, we do subtraction using our derived fractions.

30/3 - 17/3 = (30-17)/3 = 13/3

Lastly, we simplify the improper fraction. Improper fraction is a fraction whose numerator is greater than its denominator. Its simplified form is a mixed fraction.

13/3 = 4 1/3

Arliss needs to buy 4 1/3 yards more to complete the required yard length.
