<span>Let's use the quadratic formula:
2w² -</span><span><span> 20w </span>+ 50 = 0</span>
a = 2 b = -20 c = 50
x = -b +-sq root(b^2 - 4*a*c) / 2*a
x = --20 +-sq root(400 -4*2*50) / 4
x = 20 +-sq root(400 -4*2*50) / 4
x = 20 +-sq root( 0) / 4
x = 20 / 4 =5
I'd say it has one rational solution.
It does NOT have 2 solutions because the "plus / minus" section = 0.
The answer will be c
Hope it's help you
Answer:
11.7
Step-by-step explanation:
add all the numbers then divide the answer with the number of how many numbers they are
12 +15+ 6+ 8 +12+17 +10+8+ 7+ 13+ 14 +16 +8+18+11=175
175/15=11.6666666667
round the answer to the nearest whole number=11.7

x-5
Step-by-step explanation:
Answer:
Jamie has 11/15 yards of Green Felt more than Blue Felt
Step-by-step explanation:
Green felt- Blue felt
= 5/6- 1/10
= 25/30- 3/30 ( taking LCM)
= 25 - 3/30
=22/30
=11/15 yards
LCM= 2*3*5= 30
Factors of 6= 2*3
Factors of 10= 2*5
