If there are two real solutions to the equation x^2 + 4x + c = 0, which is a possible value of c?
kvasek [131]
\bf \begin{array}{lcccllll}
1x^2 &+ 4x &+ c\\
\uparrow &\uparrow &\uparrow \\
a&b&c
\end{array}\qquad discriminant\implies b^2-4ac
\\ \quad \\
\textit{if the discriminant is}
\begin{cases}
positive\to &\textit{two solutions}\\
0\to &\textit{one solution}\\
negative\to &\textit{no solution}
\end{cases}

so.. check your "c" choices, to see which one gives you a positive discriminant

Alex's work for the following quiz problem is as follows: Is Alex correct? if it's incorrect, what is the correct solution?
exis [7]

Answer:

see explanation

Step-by-step explanation:

\sqrt{10} and \sqrt{5} cannot be simplified as they are already in simplest form.

Note that \sqrt{10} + \sqrt{5} ≠ \sqrt{15}

Thus

2\sqrt{10} + 5\sqrt{5} ← cannot be simplified any further

The length of a rectangular plot of land is 10 yards more than its width if the area of the land is 600 yd.² find the dimensions
Andrews [41]

Answer:

The dimension of the plot is 30 yd by 20 yd

Step-by-step explanation:

Given;

Area = 600 yd^2

Length = width + 10

l = w + 10 ......1

Area of a rectangular plot is;

Area A = length × width

A = l × w

Substituting equation 1;

A = (w+10) × w

A = w^2 + 10w

600 = w^2 + 10w

w^2 +10w -600 = 0

Solving the quadratic equation;

w = -30 or 20

cannot be negative

w = 20 yd

l = w+10 = 20+10 = 30yd

The dimension of the plot is 30 yd by 20 yd
