Answer:
x^2-2x-4=0
Δ=2^2-4*1*(-4)
Δ=4+16=20
VΔ=2V5
x1= (2+2V5)/2=1+V5
the answer is D
Step-by-step explanation:
Answer:
18.96 / 12 = 1.58
1.58 = the cost of 1 rose
1.58 X 5 = $7.9
Answer:
24 inches
Step-by-step explanation:
15 divided by 3 equals 5, so you need to do to the other side. Which would be X divided by 3 equals 8. 24 divided by 3 equals 8
6(c+4)
In order to solve this problem you need to divide both coefficients by 6 and factor the rest out.
1/5 is greater because
10/50
20/100
15% is only 15/100
