<u>Trigonometry</u>
[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Leg <em>a</em> = <em>x</em>
Leg <em>b</em> = 12
Hypotenuse <em>c</em> = 13
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in variables [Pythagorean Theorem]: x² + 12² = 13²
- Evaluate exponents: x² + 144 = 169
- [Subtraction Property of Equality] Subtract 144 on both sides: x² = 25
- [Equality Property] Square root both sides: x = 5
Answer:
Step-by-step explanation:
24 * 12 is 288
45 * 13 is 585 + 288 is 873
Split the second term in 3a^2 - 8a + 4 into two terms
3a^2 - 2a - 6a + 4 = 0
Factor out common terms in the first two terms, then in the last two terms.
a(3a - 2) -2(3a - 2) = 0
Factor out the common term 3a - 2
(3a - 2)(a - 2) = 0
Solve for a;
a = 2/3,2
<u>Answer : B. (2/3,2)</u>
Since there are same number of either side, hence the solution has infinite number of solution
<h3>System of equations</h3>
System of equations are equation that consist of two or more equations with unknown variables.
Given the equations
2x - y = 7
2y = 4x - 14
This can also be written as
2x - y = 7
y = 2x - 7
Substitute equation 2 into 1
2x - (2x - 7) = 7
2x-2x+7= 7
7 = 7
Since there are same number of either side, hence the solution has infinite number of solution
