Answer:

(I am assuming that you don't need the answer, but just an explanation of what to do.) Let's take the first problem for an example the first thing you are going to do is subtract 12 on both sides and you will get n> -1 so then you will put a open circle on -1 going to the right.

Hope this helps :)

$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's solve for x ~

$\qquad \sf \dashrightarrow \: {x}^{2} + 5x + 6 = 0$

$\qquad \sf \dashrightarrow \: {x}^{2} + 3x + 2x + 6 = 0$

$\qquad \sf \dashrightarrow \: {x}^{}( x+ 3) + 2(x + 3)= 0$

$\qquad \sf \dashrightarrow \: {}^{}( x+ 2)(x + 3)= 0$

$\begin{cases} \sf \: x = - 2 \: \: \: \: \: \: \: \sf if \: (x + 2) = 0 \\ \\ \sf \: x = - 3 \: \: \: \: \: \: \: if \: (x + 3) = 0\end{cases}$

I hope that helps ~

Answer:

Area of triangle = 20 square yards

Step-by-step explanation:

The height of triangle = 5 yd

The base of triangle = 8 yd

We need to find area of triangle.

The formula used is: $Area\: of\: triangle=\frac{1}{2}\times base \times height$

Putting values and finding area

$Area\: of\: triangle=\frac{1}{2}\times base \times height\\Area\: of\: triangle=\frac{1}{2}\times 8 \times 5\\Area\: of\: triangle=4 \times 5\\Area\: of\: triangle=20\:square\:yards$

So, Area of triangle = 20 square yards

Evaluation the given expression for x=13. 4x+7 =?

aleksandr82 [10.1K]

The unknown value is 59

Substitute in 13 for x in the expression 4x+7. The new expression will look like 4(13)+7 after substituting. Next multiply 4 by 13 which will give you 52. The new expression will be 52+7, now add and you’ll have 52+7=59
