Answer:
<h2>4 is the right answer</h2>
<h2>2 × 2 = 4</h2>
<h3>2 × 1 = 2 </h3><h3>2 × 2 = 4</h3><h3>2 × 3 = 6 </h3><h3>2 × 4 = 8</h3><h3>2 × 5 = 10</h3><h3>2 × 6 = 12</h3><h3>2 × 7 = 14</h3><h3>2 × 8 = 16</h3><h3>2 × 9 = 18</h3><h3>2 × 10 = 20</h3>
<h2>Why is 2+2=4 and 2x2=4? </h2>
<h3>Originally Answered: why does 2*2=4 and 2+2=4? The truth is that a number multiplied by itself does not have to be equal to the same number added to itself. We can prove 2x2=4 easily. We have 2 groups of 2s.</h3>
Answer:
42 inches
Step-by-step explanation:
Factorization: (x + 4)∧2=0
Solutions based on Factorization: x + 4 = 0 ⇒ X∨1 = X∨2 = -4
Using the Fundamental Counting Theorem, it is found that 80 different scores are possible if everyone gets at least one point.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:

There are 4 darts, and for each dart 3 possible scores, hence:

Hence the number of possible scores, removing the one score with zero points on all four rounds, is:
N = 3 x 3 x 3 x 3 - 1 = 80.
