Factorising quadratic expressions

Multiply these brackets to remind yourself how to factorise.

<span><span>( x + 2 ) ( x + 5 ) = x2 + 7x + 10</span><span>( x + 2 ) ( x + 3 ) = x2 + 5x + 6</span><span>( x - 3 ) ( x - 5 ) = x 2 - 8x + 15</span><span>( x + 6 ) ( x - 5 ) = x2 + x - 30</span><span>( x - 6 ) ( x + 5 ) = x2 - x - 30</span></span>

Perimeter of rectangle is 48 inches area is 40 inches what are the length of the side
Aloiza [94]
\bf \textit{perimeter of a rectangle}=p=side+side+side+side&#10;\\\\&#10;or\implies p=w+w+l+l\implies p=2w+2l&#10;\\\\&#10;p=2(w+l)\qquad &#10;\begin{cases}&#10;w=width\\&#10;l=length\\&#10;------\\&#10;p=48&#10;\end{cases}\implies 40=2(w+l)\\\\&#10;-----------------------------\\\\&#10;\textit{area of it}=A=w\cdot l\qquad \begin{cases}&#10;w=width\\&#10;l=length\\&#10;------\\&#10;A=40&#10;\end{cases}\implies 40=wl\\\\&#10;-----------------------------\\\\

\bf thus\qquad &#10;\begin{cases}&#10;40=2(w+l)\to \frac{40}{2}=w+l\to\frac{40}{2}-l=\boxed{w}&#10;\\\\&#10;40=wl\\&#10;--------------\\&#10;40=\left( \boxed{\frac{40}{2}-l} \right)\cdot l&#10;\end{cases}

SOMEONE HELP ME PLEASE
Nikolay [14]

Answer:

<h3>Angle 6 = 101°</h3><h3>Angle 5 = 79°</h3><h3>Angle 7 = 79</h3>

Step-by-step explanation:

Angle 6 will 101°

This is because we can see that Angle 4 is alternate interior angle to Angle 6 and alternate interior angles are always equal.

<h2>So angle 6 will be 101°</h2>

Angle 7 = 79°

Here we can see that Angle 6 and angle 7 are supplementary which means it has a measure of 180°

So the value of Angle 7 will be

180 - 101 = 79

<h2>Hence the measure of angle 7 will be 79°</h2>

Angle 5 = 79°

Angle 7 and Angle 5 is vertically opposite to each other and we know that vertically opposite angles are always equal so the measure will be 79°

<h3>Hence the measure of Angle 5 will be 79°</h3>
