Answer:
7
Step-by-step explanation:
When you match the form
... ax² + bx + c = 0
to the equation
... 3x² + 5x + 7 = 0
it is reasonable to conclude that ...
... a = 3, b = 5, c = 7.
_____
The question presumes you are familiar with the form
... ax² +bx +c = 0
which is often used as the representation of a general quadratic equation. This lets us use a, b, and c instead of specific numbers, to talk about ways of factoring, graphing, or solving equations like this.

Answer:
100 or 150 units of the product.
Step-by-step explanation:
R = x(1000-4x)
What is the value of x if R = 60,000?
x(1000-4x) = 60000
-4x^2 + 1000x = 60000
x^2 - 250x = -15000
x^2 - 250x + 15000 = 0
Factorize:
(x-100)(x-150) = 0
x-100 = 0 V x-150 = 0
x = 100 V x = 150
Answer:
A = 20% B = 36%
Step-by-step explanation:
35 in total bought
2/10 = who bought model A = 20%
16+9 = 25 => 9/25 who bought model B = 36%
