1/4 = x/12 1/4 = 3/12
4 * 3 = 12
1 * 3 = 3
x = 3
1/2 b-39=101
+39 +39
1/2 b= 140
2(1/2) b= 140(2)
b=280
Answer:
89 2 irrational roots
Step-by-step explanation:
The discriminant Is b²-4ac when the equation is in the form
ax²+bx+c so in the equation
a=2 b=5 and c=-8
plug into the equation for the discriminant
so 5²-4(2)(-8)
25-(-64) 2 negatives make a positive so
25+64=89
since 89 isn’t a perfect square 2 irrational roots
