2/20 = 1/10 = 3/30 = 4/40
so 3 equivalent ratios can be 1/10 (or 1:10), 3/30 (or 3:30), 4/40 (or 4:40)
Answer:
no angle c is not supplementary
Step-by-step explanation:
Angle A and angle B are supplementary
A+B=180° Equation 1
The measure of angle B is equal to four times the complement of angle A
The complement of angle A=90°-A
B=4(90°-A)
B=360°-4A
Substitute the value of B in equation 1
A+360°-4A=180°
-3A=-180°
A=60°
The measure of angle A=60°
B=360°-4A=360°-4(60°)=120°
The measure of angle B=120°

Answer:
Step-by-step explanation:
Given expression:
To simplify the expression, we will use the formula (a - b)² = a² - 2ab + b².
[Where "a and b" are the first and second term in (a - b)²]
In this case, the first term of (2x - 12)² is "2x" and the second term is "12".
![\rightarrowtail (2x)^{2} - 2(2x)(12) + (12)^{2} \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\small\text{First term = a = 2x; Second term = b = 12]}](https://tex.z-dn.net/?f=%5Crightarrowtail%20%282x%29%5E%7B2%7D%20-%202%282x%29%2812%29%20%2B%20%2812%29%5E%7B2%7D%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%20%5B%5Csmall%5Ctext%7BFirst%20term%20%3D%20a%20%3D%202x%3B%20Second%20term%20%3D%20b%20%3D%2012%5D%7D)
Now, simplify the expression.
