4x^2+8x+27=88 consider the given equation. in order to solve by completing the square what number should be added to both sides of the equation? how many of the solutions to the equation are positive? what is the approximate value of the greatest solution to the equation rounded to the nearest hundredth?

Answer with explanation:

The given expression is:

 ⇒ 4 x^2+8 x+27=88

Dividing both sides by,4, we get

→There are two solutions of this equation, one is

 x = 3.33, which is positive

and other, x= -5.33, which is negative.

→As,the expression contains, square of ,(x+1), so, added and subtracted 1 to (x+1)².

→One Solution is Positive.

→Greatest positive Solution , x= 3.33

→Greatest Negative Solution , x=-5.33

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

im pretty sure its
