Sagot :
1)r = 18.2
2) Square root of 56 = 7.48
3)Square of -4.7 = 22.09
4) Square of 7.6 = 57.76
5) -tz = l/r
6) r = -2/5
Factoring
To include something when you are doing a calculation, or when you are trying to understand something: People are earning more, but when inflation is factored in, they are no better off.
1) r=6r-91 (Factoring)
r-6r = - 91
-5r = -91
r = 91/5
r = 18.2
Square Root
Square root, in mathematics, a factor of a number that, when multiplied by itself, gives the original number. For example, both 3 and –3 are square roots of 9.
2) -2r" -146 = -34 (Square Roots}
- 2r’’ = -34 + 146
- 2r’’ = 112
-r’’ = 112/2
-r’’= 56
r’’ = - 56
Square root of 56 = 7.48
3) r-14r-53 = 9 (Completing the Square)
- 13r = 9+53
- 13r = 62
- r = 62/13
r = - 4.7
Square of -4.7 = 22.09
4) 3r*+6r-62 =7 (Completing the Square)
9r = 7+62
r = 69/9
r = 7.6
Square of 7.6 = 57.76
5) -rtZr=l (Quadratic Formula)
- r(tz) = l
- tz = l/r
6) 5r =-2 (Quadratic Formula)
r = -2/5
