The answer for that question is Angle bisectors
Answer:
We want to expand the expression:

We can just do it by brute force, this is:
First, rewrite our expression as the product of two square factors:

Now we can expand each one these two factors:

That can be simplified to

Now we can replace that in our original expression to get:

Now we can expand that last product, to get:

We can simplify that to:

That is the expanded expression.
Answer:
Mean time and 13
Step-by-step explanation:
Given that
here is a five people and they spend the work in 7,10,13,20,15 hours respectively
Therefore here the concept i.e. used is average time or the meantime
And, this can be determined below:
= Sum of observations ÷ number of observations
= (7 + 10 + 13 + 20 + 15) ÷ 5
= 13
Answer:
3.77
Step-by-step explanation:
A= L × W
52=(W + 10)W
52= W^2 + 10W
0 = W^2 + 10W - 52
Factor from here using quadratic formula to find the roots:
W = 3.77
or
W = -13.77
Dimensions of a shape cannot be negative, therefore it's approximate width is 3.77yd.
