Answer:
8
Step-by-step explanation:
Add all the numbers and then divide them by how many numbers there are.
(14 + 2 + 12 + 11 + 2 + 14 + 3 + 2 + 12) = 72
72/9 = 8

ANSWER
D.
EXPLANATION
We want to find the expression which is a square of a binomial.
In other words, we want to identify the expression which is a perfect square trinomial.
This expression can be rewritten as,
This is a perfect square trinomial that can be factored as:
This is the square of a binomial.
The correct answer is D
Answer:
The length of v is 6 inches
Step-by-step explanation:
Here, we want to calculate the length of v to the nearest inch
The best way to go about this is to use the sine rule
But before we proceed, we need the measure of angle V
Mathematically, since we have a triangle
W + U + V = 180
This is the sum of angles in a triangle
56 + 117 + V = 180
V = 180-56-117
V = 7 degrees
so we proceed to use sine rule to get the length of v
Mathematically;
v/Sin V = u/Sin U
Thus;
v/sin 7 = 44/sin 117
v = 44sin 7/sin 117
v = 6.018
This is approximately 6 inches
