Rewrite the equation by completing the square.

dlinn [17]

Answer:

(x + 1/2)^2 = 289/4

Step-by-step explanation:

x^2+x-72=0

Write like this:

(x + ___)^2 = ___

put 72 on other side

x^2 + x = 72

x^ + x + (1/4) = 72 + (1/4)

(x + 1/2)^2 = 289/4

x + (1/2) = 17/2

A device used in golf to estimate the distance d, in yards, to a hole measures the size s, in inches, that the 7-ft pin appears

Nesterboy [21]

This is a proportional problem.
The distance 'd' corresponds to the 9 inches.
The 7-ft pin corresponds to the size 's'.

Convert 7ft to 7/3 yds. This way you have equal ratio of yds to inches.

$\frac{d}{9} = \frac{7/3}{s} \\ \\ d = \frac{21}{s}$

The sum of 3 consecutive odd numbers is 183 whats the second number im this sentence

Naddik [55]

Answer:

The second number is 61

Step-by-step explanation:

It's implied that the first integer is odd.

Since the consecutive intergers are odd, use an equation that looks like this:

(x+2) + (x+2) + (x+2) = 183 and simplify

*If you add 2 to an odd number, you get the next odd number. That's why I used 2*

3x + 6 = 183 → 3x = 177 → x = 59 which means the first integer is 59. The consecutive integers is 59, 61, 63.

Which value of f makes 3f+5=32 a true statement?<br> a. f=6 <br> b. f=8 <br> c. f=9<br> d. f=12

DIA [1.3K]

We just need to solve the equation in order to find the value.

$3f+5=32$

So we subtract 5 from both sides of the euqation and get

$3f=27$

Now we divide by 3 on both sides and get

$f=9$

So the answer is C.

Hope this helps!
