Hi!
I can help you with joy!
3 moons+1 star equals 29.
All right.
Actually, there are a few numbers that can be hidden behind the moon:
3*8=24 + 1 star (5) = 29
But 1 moon + 1 moon equals 15.
So one moon equals 7.5.
Plz help. pl and thank u

Answer:
2, -6
Step-by-step explanation:
x^2 + 4x - 12
A = 1
B = 4
C = -12
i used the "X" method to solve for the solutions. i think it's easier than using the quadratic formula but it doesn't always work
for the "X" method you have to multiply your A value and your C value together so 1 x (-12) = -12. that is going to be the top part of the X
the bottom part of the x will be your B value which is 4
we have to find multiples of -12 that will also add to 4
so -2 and 6 multiply to -12 but also add to 4 so we know these numbers will work
i added added two drawings to show how i found the solutions using the "X" method and the quadratic formula
