Explanation:
Divide the negative 16 by 2= -8
Then square -8
So the missing constant is 64
The perfect square would be (x-8)^2
50 degrees is one while the other two are 130 degrees
Answer:
x = 98
Step-by-step explanation:
The sum of the interior angles in a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 7, thus
sum = 180° × 5 = 900°
Sum the interior angles and equate to 900
x + 146 + 122 + 142 + 140 + 110 + 142 = 900, that is
x + 802 = 900 ( subtract 802 from both sides )
x = 98
This is the solution

Answer:
We do not have the equation for the part B, so we can not aswer it correctly.
But i will give a general answer.
We could have infinite answers always when we have more variables than linear independent equations:
This is, if we have one variable, x, we can have infinite solutions if we have no equations (or equations with no restrictions for our variable)
So if we have an equation like:
x*4 = √16*x
you can see that both sides of the equation are exactly the same, so this equation actually does not have any value, and x could take infinite different values and the equation will remain true.
If we have two variables, x and y, we will have infinite solutions if we have only one equation:
y = a*x + b
We have infinite pairs (x, y)
