Answer:
Option D: 3x2 + 2x - 1
Step-by-step explanation:
Given that:
=(5x2 - 5x + 3
)- (2x2 +7x- 4)
As we have to subtract them so by simplifying:
"-" sign will alter all signs in the bracket
= 5x2 - 5x + 3 - 2x2 + 7x - 4
Now by adding same terms
= 5x2 - 2x2 - 5x + 7x + 3 -4
= 3x2 + 2x - 1
i hope it will help you!

Answer:
T = 2
Step-by-step explanation:
Fill in the given numbers and solve for T.
I = PRT/100
80 = 400·10·T/100
80 = 40T . . . . . . . . . . . . simplify
80/40 = T = 2 . . . . . . . . divide by the coefficient of T

A heptagon has 7 sides.
Sum of all interior angles = (7 - 2) x 180 = 900°
900 - 776 = 124°
Answer: The final angle must be 124°
I think it is a direct variation because if you divide 9/3, 27/3, 39/13, and 60/20 it will all give you the same number which is 3.
I hope this helps.
