Set each binomial equal to zero to solve. 

2n + 3 = 0
2n = - 3
n = - 3 / 2

n - 4 = 0
n = 4

So n = -3/2, 4

Why is the value of q?
Rudiy27

Given:

QSR is a right triangle.

QT = 10

TR = 4

To find:

The value of q.

Solution:

Hypotenuse of QSR = QT + TR

                                 = 10 + 4

                                 = 14

Geometric mean of similar right triangle formula:

$\frac{\text { hypotenuse }}{\text { leg }}=\frac{\text { leg }}{\text { part }}$

$\Rightarrow \frac{14}{q} =\frac{q}{4}

Do cross multiplication.

$\Rightarrow14\times 4 =q\times q

$\Rightarrow 56 =q^2

Switch the sides.

$\Rightarrow q^2 =56

Taking square root on both sides.

\Rightarrow q =2 \sqrt{14}

The value of q is 2 \sqrt{14}.

An isosceles triangle has a perimeter of 18 cm. Find a function that models its area A in terms of the length of its base b.
IgorLugansk [536]
So.... notice the picture below

now, we know what the "height" or "altitude" is
now, we also know the perimeter is 18cm

so, k + k + b = 18
or 2k + b = 18
thus  \bf k=\cfrac{18-b}{2}

so... one can say that \bf \textit{area of a triangle}=A=\cfrac{1}{2}bh\qquad &#10;\begin{cases}&#10;b=b&#10;\\\\&#10;h=\sqrt{k^2-\left( \frac{b}{2} \right)^2}&#10;\\\\&#10;h=\sqrt{k^2-\frac{b^2}{4}}\\&#10;--------------\\&#10;k=\frac{18-b}{2}\qquad thus\\&#10;--------------\\&#10;h=\sqrt{\left( \frac{18-b}{2} \right)^2-\frac{b^2}{4}}&#10;\end{cases}\\\\&#10;-----------------------------\\\\&#10;A=\cfrac{1}{2}\cdot b\cdot \sqrt{\left( \frac{18-b}{2} \right)^2-\frac{b^2}{4}}

and you can simplify it if you wish.. not sure you have to
