The answers are 6ft & 4ft
Answer:
Jim + June + Alex = 82 (x+9) x + (x-8) = 82 3x +1 = 82 3x = 82 - 1 = 81 x = 81/3 = 27. ANSWER. June is 27 years old; Jim is 27+9 = 36 years old; Alex is 27-8 = 19 years old.
Answer:
we have 2 real solutions
Step-by-step explanation:
ax^2 + bx+c
discriminant
b^2-4ac
6x=-2x^2-3
subtract 6x from each side
0 = -2x^2 -6x-3
a= -2
b=-6
c=-3
b^2-4ac = (-6)^2 - 4(-2) (-3)
36 - 24
12
if > 0 2 real solutions
= 0 1 real solution
< 0 2 complex solution
since 12 > 0 we have 2 real solutions
Answer: x=+2
Step-by-step explanation:2x-6=12x-26
We move all terms to the left:
2x-6-(12x-26)=0
We get rid of parentheses
2x-12x+26-6=0
We add all the numbers together, and all the variables
-10x+20=0
We move all terms containing x to the left, all other terms to the right
-10x=-20
x=-20/-10
x=+2
