Answer:
Step-by-step explanation:
The area of a rectangle is:
First let's write both the length and the width in terms of x:
<u>How we obtained the answer</u>:
The question states the length is "2 less than x". In this case, "less" is a keyword that represents subtraction. Therefore, "2 less than x" is "x-2".
<u>How we obtained the answer</u>:
The question states the width is "5 less than twice of x". First, start by figuring out what "twice of x" is. The keyword is "twice" which represents multiplication. Therefore, "twice of x" can be written as "2x". Then, using the same keyword from before ("less"), "5 less than..." represents "2x-5".
Given:
Area = 56 cm
Find:
x
FOIL (Firsts, outsides, insides, lasts):
Subtract 10 from both sides:
Subtract 46 from both sides (forms a quadratic equation):
Use the quadratic formula:
where
Therefore:
The answer is:
This is because if we used subtraction, we would get a negative value, and we cannot have a negative length/width.
Answer:
Step-by-step explanation:
The general equation of a line:
In our case <em>a</em> is given
Now we plug in for <em>a</em> and we get:
Now we plug in our coordinates into this equation and we solve for <em>b</em>
So the equation of the line is
