Answer:
12
Step-by-step explanation:
A₃ = 3 * 2⁽³⁻¹⁾ = 3 * 2² = 3 * 4 = 12
The simplified form is 13x+5
You first add 2x and 11x, where you will get 13x, and from there, you subtract 4 from 9, where you will get 5, resulting in the answer of 13x+5.
Hope this helps :)
The mid-point of the numbers 3.8 and 4.1 will be 3.95.
<h3>What is the midpoint of line segment AB?</h3>
Let C be the mid-point of the A and B.
C = (A + B) / 2
The numbers are given below.
3.8 and 4.1
Then the mid-point of the numbers 3.8 and 4.1 will be
C = (3.8 + 4.1) / 2
C = 7.9 / 2
C = 3.95

The comparison of the lengths of the sides based on the angles are given
by sine rule.
The lengths of the sides from greatest to least are;
Reasons:
The given parameters are;
∠A = 78°, ∠B = 56°, ∠C = 46°
By sine rule, we have;
Given that, sin(46°) ≈ 0.719, sin(56°) ≈ 0.829, sin(78°) ≈ 0.978, we have;
sin(78°) > sin(56°) > sin(46°)
Therefore, applying equal proportions of similar ratios, we have;
<u>BC > AC > AB</u>
