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

Using the distributive property what is 2(-5+3) as an equivalent expression

photoshop1234 [79]

Answer:

-4

Step-by-step explanation:

Because when distrubuting first you distribute 2(-5) which gives you -10 and then you distribute 2 into 3 which is 2(3) which gives you 6. So now you have -10+6. So you can further simplify that into -4. We get -4 because -10 + 6 is -4. And the 4 is negitive because there are more negitives than positives.
