Answer:
the answer is 60/100 60%
Step-by-step explanation:
An algebraic expression for <em>Sum of a and 5 divided by 8</em> is
We need to express the given statement as an algebraic expression.
Sum of a and 5 divided by 8
Basically, we are given the expression in English sentence and we have to write algebraic expression.
It can be done in two steps:
Sum of a and 5 = We know that sum is denoted by + sign. So, we get (a+5)
Sum of a and 5 divided by 8 =
So, An algebraic expression for <em>Sum of a and 5 divided by 8</em> is

2(x + 2)² - 5
Given
2x² + 8x + 3
To obtain the required form use the method of completing the square.
The coefficient of the x² term must be 1, thus factor 2 out of 2x² + 8x
= 2(x² + 4x) + 3
add/subtract ( half the coefficient of the x- term)² to x² + 4x
= 2(x² + 2(2)x + 4 - 4) + 3
= 2(x + 2)² - 8 + 3
= 2(x + 2)² - 5
with p = 2 and q = - 5
