Answer:
A
Step-by-step explanation:
x2 = -98
x =+-√-98
x = +-√49 • 2 • -1
x = +-7√2 • -1
x = +-7i√2
(Note: i = √-1 and i^2 = -1, so you can interchange the values)
Answer:
1.x^2-5x
2.2x^2+15x+18
3. x^2+20x+18
Step-by-step explanation:
1. x(x-5) x*x-5*x = x^2-5x
2. (x+6)(2x+3) x*2x+x*3+6*2x+6*3= 2x^2+15x+18
3.(2x^2+15x+18)-(x^2-5x)=x^2+20x+18
Answer:
Step-by-step explanation:
George is g and Mike is m
Substitute g in the second equation
- 2m - 5 + m = 31
- 3m - 5 = 31
- 3m = 36
- m = 12
Finding g
- g = 2*12 - 5 = 24 - 5 = 19
Answer:
1- 12 inches
2- 12 x .7=8.4 inches next biggest doll
3- 8.4 x .7=5.88 inches next biggest doll
4-5.88 x .7=4.12 inches the last doll.

Answer:
Landon is 11 years old
Step-by-step explanation:
