Answer:
x = ±3
Step-by-step explanation:
x^2 +3 = 12
Subtract 3 from each side
x^2 +3-3 = 12-3
x^2 = 9
Take the square root of each side
sqrt(x^2) =±sqrt(9)
x = ±3
it is 120 or the second one

Multiplication
Answer:
A) 4.5
Step-by-step explanation:
you can set up a ratio comparing AB/CB to (AB + BD)/5
3/2 = 3 + BD/5
cross-multiply to get 15 = 2(3 + BD)
15 = 6 + 2BD
9 = 2BD
9/2 = BD
Answer:
The answer is (4,-2)
Step-by-step explanation:
y=x-6
3x+2y=8
3x+2(x-6)=8
3x+2x-12=8 Combine like terms
3x+2x-12+12=8+12 add 12 to both sides then combine
5x=20→ x=4
then plug it in to y=x-6→y=4-6→y=-2
