Answer:
219.1
Step-by-step explanation:
Mean: Add all numbers together and divide by the amount of numbers
Numbers added together = 2,191
2,191/10 = 219.1
Answer:
Step-by-step explanation:
i think 45 because a square could be broken up into 4s
To solve quadratics, the most correct and effective way, in my opinion, is the quadratic formula:
<span><span>
Plugging it in, we get:
</span></span>
So the final answer is:
and
First we will compute the h+k and then multiply the result by 2.
To add polynomials, we add terms whose variables are alike, for example:
we add the coefficients of x^2 together, the coefficients of x together and so on.
Therefore:
h + k = x^2 + 1 + x - 2 = x^2+x-1
Now, we will multiply this answer by 2 to get the final answer:
2(h+k) = 2(x^2+x-1) = 2x^2 + 2x -2
The answer is:
The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
