Answer:
4
Step-by-step explanation:
Calculation of the discriminant of the polynomial : x⋅2−4⋅x+5
1. Applying the formula to calculate the discriminant Δ=b2−4⋅a⋅c with : a=0, b=−2,c=5
2. Δ=(−2)2−4⋅(0)⋅(5)=4=4
3. The discriminant of the polynomial x⋅2−4⋅x+5 is equal to 4
Answer:
9 divided by 5 is the same as 9/5
Answer:
It would be 5
Step-by-step explanation:
5 equals everything that is 5 or 10
for example, 5 * 5 equals 25
Odd numbers times 5 equals a odd number with the 5 at the end
Even numbers times 5 equal an even number with a 0 at the end
I hope that helped
AD = AB
2r + 8 = 5r - 13
3r = 21
r = 7
AD = 2r + 8 = 2(7) + 8 = 14 + 8 = 22
answer AD = 22
