Please help me ive never done one like this
inessss [21]

Given:

DE = (6x - 9) cm

EF = (4x + 4) cm

LM = 14 cm

MN = 16 cm

To find:

The value of x.

Solution:

<em>If three or more parallel lines intersect two transversals, then they cut off the transversals proportionally.</em>

$\Rightarrow \frac{DE}{EF} =\frac{LM}{MN}

$\Rightarrow \frac{6x-9}{4x+4} =\frac{14}{16}

Do cross multiplication.

$\Rightarrow 16( {6x-9})=14 ({4x+4} )

$\Rightarrow 96x-144=56 x+56

Add 144 on both sides.

$\Rightarrow 96x-144+144=56 x+56+144

$\Rightarrow 96x=56 x+200

Subtract 56x from both sides.

$\Rightarrow 96x-56x=56 x+200-56x

$\Rightarrow 40x=200

Divide by 40 on both sides, we get

$\Rightarrow x=5

The value of x is 5.

The base of a triangle is represented by (2x − 6) and the height by (x − 2). Which polynomial expression BEST represents the are
BabaBlast [244]
Area of a triangle= \frac{1}{2} *base*height
A=\frac{1}{2} *(2x-6)*(x-2)
A=\frac{1}{2} ( 2x^{2} -4x-6x+12)
A=x^{2} -2x-3x+6
A=x^{2} -5x+6
