Answer:
$10.80
Step-by-step explanation:
$2.40 + $2.80(3)
$2.40 + 8.40
The ratio is rational and by multiplying or dividing the numbers included in the ratio by the same number, it's just like taking a fraction and taking it out of simplest form, it doesn't change the value of the ratio or the fraction in simplest form, it just changes the numbers
4188.79 would be de answer. Hope that helps.
The correct quadratic equation;
x2+7x-2=0
Working
Assuming the frame has a uniform thickness;
Then length of mirror and frame is 3+x and width 2+x
The area of mirror and frame area;
A=L*W
8=(3+x)(2+x)
8=(6+5x+x2)
Taking 8 to the Right hand side, we have:
x2+5x-2 =0
Answer:

Step-by-step explanation:
Given:
The given inequality is:

The given inequality has variable 'x' on both sides of the inequality.
In order to solve such inequalities, we bring the variables on the same side as the first step in solving for 'x'.
Therefore, we could either add
on both sides or add
both sides to bring the variable terms on same side.
If we add
both sides, we get:

So, among all the given options, third option matches the above inequality.
Therefore, the first step in solving the given inequality is
