Answer:
option D.Given and reflexive property.
Answer:
1,5
Step-by-step explanation:
if x^2=40 you would need to square root both sides to get x alone therefore x=6.3
Answer:
x^2+17x+91=0
a = 1; b = 17; c = +91;
Δ = b2-4ac
Δ = 172-4·1·91
Δ = -75
Delta is less than zero, so there is no solution for the equation
