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

Answer: The altitude of the smaller triangle is 14.4 inches
Step-by-step explanation:
Two similar triangles have a scale factor of 3:5. This can also be expressed as 3/5
The altitude of the larger triangle is 24 inches. The difference in altitude or other lengths of the two similar triangles is linear. To determine the altitude of the smaller triangle, let us assign x to the altitude of the smaller triangle. It means that 3:5 = x : 24. Therefore
3/5 = x/24
Cross multiplying, it becomes
5x = 3×24 = 72
x = 72/5 = 14.4
