Answer:
Step-by-step explanation:
A) 3x²c² + 5xc² - 2c²
Factor c² from all terms in the expression.
c²(3x² + 5x - 2)
Factor 3x² + 5x - 2
c²(3x-1)(x+2)
B) x² + 6x + 9
x² + 3x + 3x + 9
Factor common terms.
x(x+3)+3(x+3)
Take x+3 common.
(x+3)(x+3)
C) x² - 9
x² -3²
Apply formula : a² - b² = (a+b)(a-b)
(x+3)(x-3)
Since the given angle is less than 60 degrees which is less than 90 degrees, hence the measure that would be classified as the given angle is acute angle.
<h3>Lines and angle</h3>A line is the shortest distance between two points where. the points where two lines meet is an angle.
There are several types of angles including acute, obtuse, right and straight
For acute angle, the angle is less than 90 degrees
For obtuse, the angle is greater than 90 and less than 180 degrees
For right angle, the angle is 90 degrees
Since the given angle is less than 60 degrees which is less than 90 degrees, hence the measure that would be classified as the given angle is acute angle.
