Answer:
the area of rectangle A is 133.33 sq cm
Step-by-step explanation:
let us suppose area of rectangle A be x....hence we get ,
3:5=80/x
or,3/5=80/x
or,3x=80*5
or,x=400/3
x=133.3.3
Answer: q=26
Step-by-step explanation:
First you must acknowledge that you are dealing with a line therefore you must write linear equation or linear function in this case.
Linear function has a form of,

Then calculate the slope <em>m</em> using the coordinates of two points. Let say <em>A(x1, y1)</em> and <em>B(x2, y2)</em>,

Now pick a point either <em>A</em> or <em>B</em> and insert coordinates of either one of them in the linear equation also insert the slope you just calculated, I will pick point <em>A</em>.

From here you solve the equation for n,

So you have slope <em>m</em> and variable <em>n</em> therefore you can write down the equation of the line,

Hope this helps.

The two fractions are divisible by 2, can be broken down
The answer is true. We know this because 9^2 - 6^2 is 45.
