Answer:
Hello,
answer C : -3x²-3x-2=0 (or 3x²+3x+2=0)
Step-by-step explanation:
A: delta=12²-4*2*18=0 not negative
B: delta= 5²+4*3*1=37 not negative
C: 3x²+2x+2=0, delta=2²-4*3*2=16-24=-8 is negative: roots are complex
D: delta 16²-4*2*2=240 not negative
Answer:

Answer:
the distance is 9.1 inches (please give brainliest)
Step-by-step explanation:
we must use the pythagorean theorem:
5.7^2 + 7.1^2 = c^2
(c being the distance being the two corners)
c^2 = 82.9
c = sqrt(82.9) ≈ 9.1
I think you forgot to mention Susan's current age if not:
x+5
x-4
6x
Answer:
First one is c because 3 1/2 - 1/2=3
Second one is also c because 0.9x2=1.8
And third one c is because 2 2/3:3/1=1 1/8
