Step-by-step explanation:
y - y = 2x + 150 -( - 8x - 30 )
0 = 2 x + 150 + 8 x + 30
0.= 10x + 180
- 180 = 10 x
-180/10 = x
-18 = x
then y = 2 (-18) + 150
y = -36 + 150
y = 114

Step-by-step explanation:
Answer:
Step-by-step explanation:
no of sides (n)=11
sum=(n-2)180
=(11-2)180
=9*180
=1620
therefore sum of the interior angles of a polygon having 11 sides id 1620°.
Answer:
136.2
Step-by-step explanation:
Plugin x = 18 in the polynomial.
P(x) = 0.02x³ + 0.04x² + 0.3x + 1.2
P(18)= 0.02*(18)³ + 0.04*(18)² + 0.3*18 + 1.2
= 0.02 * 5832 + 0.04*324 + 5.4 + 1.2
= 116.64 + 12.96 + 5.4 + 1.2
= 136.2
