Answer:
Step-by-step explanation:
a) 3x + 8x + 4x + 3x = 360
18x = 360
x = 20
Angles are : 60, 160, 60, 80
b) 8y + 2y = 360
10y = 360
y = 36
Angles are : 72 , 288
c) 8p + m = 180
6p + m + 30 = 180 => 6p + m = 150
2p = 30
p = 15
120 + m = 180
m = 60
Angles are :- 120, 60, 90
A "rational expression" is a fraction in which the numerator and the denominator are both polynomials. The sum of two such expressions will always produce another such expression, viz.,
<span>p(x)/q(x) + r(x)/s(x) = [p(x)s(x) + q(x)r(x)] / [q(x)*s(x)]. </span>
<span>The numerator and denominator of the sum will both be polynomials when fully expanded</span>
