Answer:
The product of a linear monomial and a linear binomial is a second degree binomial
Step-by-step explanation:
Examples of linear monomials are:
2x
2a
y
Examples of linear binomials are:
2x+y
x-y
3a+b
x+1
When we take the product of a linear monomial and a linear bbinomial we obtain:
2a(3a+b)=6a²+2ab
y(x+1)=xy+y
y(x-y)=xy-y²
These are all second degree binomials.
Using Pythagorean theorem, the answer should be D

Answer:
Step-by-step explanation:
P = 1800 + 700x - 100x²
Find x when p = $2,800
2,800 = 1800 + 700x - 100x²
- 100x² + 700x + 1800 - 2800 = 0
-100x² + 700x - 1000 = 0
- x² + 7x - 10 = 0
a = -1
b = 7
c = -10
x = -b ± √b² - 4ac / 2a
x = -7 ± √7² - 4(-1)(-10) / 2(-1)
= -7 ± √49 - 40 / -2
= -7 ± √9 / -2
= -7 ± 3 / -2
= (-7 + 3) / -2 or (-7 - 3) / -2
= -4 / -2 or -10 / -2
x = 2 or 5
x = 2 items for smaller value
x = 5 items for larger value
