Answer:
a = 2.4
Step-by-step explanation:
The problem statement tells you ...
b/a = 6
b - a = 12
Using the first equation, we can write an expression for b:
b = 6a . . . . . . . multiply both sides by "a"
This can be substituted into the second equation to find a value for "a":
6a -a = 12
5a = 12
a = 12/5 = 2.4
The value of a is 2.4.
The carpet's proportions are 8 feet x 12 feet. If the carpet is to be 2 feet wide, we have to divide the original proportions by 4, since 8/4 = 2. So, the new proportions will be 2 feet x 3 feet.
To find the carpet's area, we must multiply the width and the length. So, the final answer is:
Area = 2 x 3 = 6 square feet
Percent x Whole= Part
60% x 65= p
60/100x65= p
.60 x 65= 39
p=39
I hope this helps!

Answer:
x = -3.73 or -0.27
Step-by-step explanation:
From the question,
x²+ 4x+1 = 0
This is a quadratic equation, and it can be solved using any of the 3 methods.
Using completing the square method,
x²+4x = -1
Add half the coeffiecient of x, square it and add it to both side of the equation.
The coefficient of x is 4,
half the cofficient is 2
Add 2² to both side of the equation
x²+4x+2² = -1+2²
(x+2)² = 3
x+2 = ±√3
x+2 = ±1.73
Either,
x+2 = -1.73
x = -1.73-2
x = -3.73
or
x+2 = +1.73
x = =1.73-2
x = -0.27
