The two numbers are -4 and -6.
- two negatives make a positive. in this case -4×-4 equals 16 and -6×-6 equals 36. these are the squares
- 16+36 equals 52

Answer:
27
Step-by-step explanation:
CDE is a right angle so the sum of CDF and FDE is equal to 90
2x + x + 9 = 90 add like terms
3x + 9 = 90 subtract 9 from both sides
3x = 81 divide both sides by 3
x = 27
1/3 for the first one, and 3/4 for the second one :)
So for me, how I would do it is move the variables and numbers to one side. So we have the equation 3x-3=2/5x+7. So you would subtract 2/5x to the left side and add 3 to the right side. The equation will then turn out to be 3x-2/5x=7+3. Much more easier right? So just simplify both side, and you will get 13/5x=10. In order to isolate x, you have to divide 13/5 in both side, leaving x= 3 11/13 or 50/13. You can always plug the answer back in to double check :)
The slope is -½, and the y intercept would be (0, -5/2)
