The perimeter of a rectangle is found by multiplying the length by 2 and the width by 2 and adding them together.
P = 2L + 2W
Filling in the information given we can find the width:
16.8 = 2(3.6) + 2W
16.8 = 7.2 + 2W
2w = 16.8 - 7.2
2w = 9.6
w = 9.6 / 2
w = 4.8 in.
Answer:
x=12
Step-by-step explanation:
ab=dc so 15=x+3 you subtract 3 from both sides... x=12
Solution
Given the quadratic equation

we need to find the zeros of the equation
To do that, we use the completing the square method
Step 1. Add 38 to both sides

Step 2: add the square of half of the coefficient of x to both sides
That is;

Step 3: Simplify the above expression;
