the answer is 70.9 percent
For this case we have a quadratic polynomial given by:
Where:
We must factor, for this we follow the steps below:
Step 1:
The term of the medium must be rewritten as the sum of two terms, whose sum is -7 and the product is :
Then, the term of the medium, fulfilling the two previous conditions, can be written as:
We check:
So, we have:
Step 2:
The maximum common denominator (the largest integer that divides them without leaving residue) of each group is factored
Step 3:
We take common factor :
Thus, the expression can be factored as:
Answer:
Answer:
x = 11/3 = 3 2/3
y = 13/3 = 4 1/3
Step-by-step explanation:
Here, we want to solve the system of equations simultaneously
x + y = 8
2x -3 = y
From the second equation, we have an equation for y
we can simply proceed to substitute this into the first equation
x + 2x - 3 = 8
3x - 3 = 8
3x = 8 + 3
3x = 11
x = 11/3
Recall;
y = 2x - 3
y = 2(11/3) - 3
y = 22/3 - 3
y = (22-3(3))/3
y = (22-9)/3 = 13/3
