These equations do match up. All you have to do is find the solution to the first equation. After that, plug in that solution to the second equation. If it makes the equation true, then the equations match.
Hope this helps!

You would think it was 3 * 12 = 36. Not so. All polygons have to be broken down into some figure that will give 2 dimensions that are at right angles to each other. That would mean that
d1 * d2 = Area for the small polygon
3d1 * 3d2 = area of the larger polygon
What that means is that the area of the larger one is 9 times the smaller one.
Area large = 12 * 9 = 108 square units. <<<<< answer.
If you find this hard to be leave try it with a square.
Suppose you have a square (the small one) that is 3 cm by 3 cm
The small one has an area of 3*3 cm^2 = 9 cm
Now you have another square that is 3 times larger. That means that each side is 3*3 = 9
So s = 9
Area = s^2
Area = 9^2 = 81 cm^2
81 is 9 times larger than 9 just as you would think.
She earned 661.50 dollars. If she worked 7.5 hrs each day Mon-Wed, she worked 22.5 hrs from Mon-Wed because 7.5 times 3 is 22.5. She also worked 6 hrs on Sat. and 5.25 hrs on Sun., so in total, she worked 33.75 hrs last week. To find out her pay, we have to multiply the total hrs by the amount she gets payed, 19.60. 33.75x19.60 is 661.50, the amount she got payed last week.
