Answer:
You can't figure it out.
You need the whole problem, the best I can do is simplify it:
Expand the polynomial using the FOIL method.

Have a nice day!
Answer:
A. The expression of "40 times the sum of 24 and 36" would be 40 x (24+36), and the value would be 2400.
B. for the words portion it would be "20 times the sum of 650 and 350", and the value of that expression is 20,000.
C. The expression of "divide the difference between 1,600 and 400 by 4" should be 1200 / 4, and if that is the correct way to format the expression then the value would be 300.
D. for the words portion it would be "100 times the sum of 78 and 12", and the value of that expression is 10,000.

Answer:
x = 14
y = 4
Explanation:
Ok so, just from looking at the two triangles i can tell they're congruent right triangles. I used different colors to show which sides of the triangle correspond and are equal to each other in my attatched photo.
So the side thats equal to x is the same length as the side that's equal to y+10 on the other triangle.
So we can write the equation x = y + 10.
Using this same method, the side that's equal to x + 2 is the same length as the side that's equal to 4y on the other triangle.
So, we can write the equation 4y = x + 2.
Now we have the equations
you could rewrite to be in slope- intercept form so they're easier to graph. But a graphing calculator online would plot it just fine.
If you graph these two equations they'll intersect at the solution ( 14, 4 ). I'll include the graph in my images as well.
To check your answer, you can plug in x and y and see if the triangle sides end up being the same length. I did and it was correct.
They are equal
15/2.49=0.166
20/3.32=0.166
