I need help with the equation inserted in the picture.

sergij07 [2.7K]

Answer:

x = 4

-4x+21 => 5

Step-by-step explanation:

The given triangle in the picture is isosceles triangle which means that two sides of the triangle are equal.

So,

$Side\ 1: -4x+21\\Side\ 2: -4x+21\\Side\ 3: 6\\Perimeter = 16$

Now

Putting all the values in equation for perimeter

$Side\ 1+Side\ 2+Side\ 3 = 16\\-4x+21 -4x+21 + 6 =16\\-8x +48 = 16\\-8x = 16-48\\-8x = -32\\\frac{-8x}{-8} = \frac{-32}{-8}\\x = 4$

Putting x = 4 in side 1

$=-4(4)+21\\= -16+21\\=5$

Hence,

x = 4

-4x+21 => 5
