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

It cost Bo $9.75 to send 65 text messages. How many text messages did he send if he spent $6.60?
VashaNatasha [74]

If we use $6.60 then 44 massages will go to be sent.

<h3>What are the ratio and proportion?</h3>

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

For example 3/8 here 3 is the numerator and 8 is the denominator the value of the fraction will be less than 1 or greater than it depends upon the numerator and denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

$9.75 ⇔ 65 text massages

Divide by 9.75

$1 ⇔ 6.67 massages,

Multiply by 6.60

$6.60 ⇔ 44 text messages.

Hence "If we use $6.60 then 44 massages will go to be sent".
