Based on the given figure above, we can conclude that the triangle is an isosceles triangle. By definition, an isosceles triangle is a triangle that has at least two equal sides. Since this is an isosceles triangle, 8x-10 =6x. Now we can solve for x. So,
8x-10 =6x
8x-6x = 10
2x =10
x= 5.
Therefore, the value of x in the figure is 5. Hope this is the answer that you are looking for.

5x + 2x + 2 = 9x + 4

bija089 [108]

Step-by-step explanation:

Given

5x + 2x + 2 = 9x + 4

9x - 5x - 2x = 2 - 4

9x - 7x = - 2

2x = - 2

x = - 2 / 2

Therefore x = -1.

<h3><u>Part A</u></h3>

$\sf \rightarrow y^2 - 3y - 4y +12$

factor the common term 'y' and '-4'

$\sf \rightarrow y(y - 3) - 4(y - 3)$

collect into groups

$\sf \rightarrow (y- 4)(y - 3)$

<h3><u>Part B</u></h3>

$\sf \rightarrow 9x^2 - 12x + 4$

middle term split

$\sf \rightarrow 9x^2 - 6x - 6x+ 4$

factor the common term '3x' and '-2'

$\sf \rightarrow 3x(3x - 2) -2( 3x-2)$

collect into groups

$\sf \rightarrow (3x -2)( 3x-2)$

simplify the following

$\sf \rightarrow (3x -2)^2$
