Answer:

  • (-2)^2 = 4
  • -2^2 = -4

Step-by-step explanation:

The first is (-2)(-2) = 4.

The second is -(2)(2) = -4.

The order of operations says exponents are evaluated first. An exponent signifies repeated multiplication of the base.

_____

If your calculator is working correctly, it will show you the difference.

__

Beware spreadsheet programs. They don't always follow the order of operations when evaluating formulas. Parentheses are often required to keep them honest.

I need help on these problems please
Alik [6]
Alright sure:
Q5: ∠3
Q6: ∠1
Q7: ∠2
Q8: x = 25
Q9: x = 63
For Questions 8 and 9 what I did was find out the supplementary angle adjacent to the exterior angle.
8: 180° in a supp. angle. So 180-105 = 75. To make a triangle it has to be 180°. So 180 - 75-80 = 25 So x=25
9: 180° in a supp. angle. So 180-135 = 45. To make a triangle it has to be 180°. So 180 - 45-72 = 63. So x=63

Let me know if you don't understand that. If you don't get it I'll explain it further for you.

Ksivusya [100]
Formula for Compound Interest

Amount = Principal * (1 + Rate/100)^Time
A = P * (1 + R/100)^T
P = A/((1 + R/100)^T) = 92000/((1 + 4.7/100)^16) = $44120.5503

triangle FGH is an equilateral triangle with FG=x+5,GH=3x-9,and FH=2x-2 . find x and the measure of each side
Zigmanuir [339]
The sides of an equilateral triangle are equal length, so ...
  GH = FH
  3x-9 = 2x-2
  x = 7 . . . . . . . . add 9-2x

Then the side lengths are
  FG = x+5
  FG = 7 +5 = 12

x = 7
FG = GH = FH = 12
