Answer:
The roots of the equation are -4 and -5

Explanation:
The general form of the quadratic equation is:
ax² + bx + c = 0
The given equation is:
3x² + 27x + 60 = 0
By comparison, we could find that:
a = 3
b = 27
c = 60

Now, to get the roots we would use the quadratic formula shown in the attached image.

By substituting, we would find that:
either x = \frac{-27+ \sqrt{(27)^2-4(3)(60)} }{2(3)}  = -4

or x = \frac{-27- \sqrt{(27)^2-4(3)(60)} }{2(3)} = -5

This means that the roots of the equation are -4 and -5

Hope this helps :)

a toy store marks down every toy by 15% in January. How much does a toy cost during January? Use p for the price in December.
satela [25.4K]

A toy cost 0.85p in January.

Step-by-step explanation:

Given,

Mark down in January = 15%

Let,

Price in December = p

Mark down in January = 15% of price in December

Mark down in January = \frac{15}{100}*p

Mark down in January = 0.15p

Price of toy in January = Price in December - Mark down

Price of toy in January = p - 0.15p = 0.85p

A toy cost 0.85p in January.
