The polygon would have 24 sides. (n-2)180 = n =24
Answer:
- 0, 3, 8, 15, 24
- y = x² + 2x
Step-by-step explanation:
<u>The pattern is</u>
- Step 1 ⇒ 1*3 = 3
- Step 2 ⇒ 2*4 = 8
- Step 3 ⇒ 3*5 = 15
<u>Next step would be</u>
<u>Step zero would be</u>
<u>The equation</u>
1a) 8 / (1/2) = 16 * 3 = 48
1b) 3sqrt(49) = 3 * 7 = 21
1c) (5+2)(-8) / (-2)^3 -3
(7*-8) / (-8 -3)
-56/-11
56/11
Answer:
Adult=58
Step-by-step explanation:
c=child, a=adult
6.4c+9.7a=1145 equation 1
c+a=149 equation 2
a=149-c modified equation 2 to isolate a
6.4c+9.7(149-c)=1145 substitute value of a from equation 1 into equation 2
6.4c+1445.3-9.7c=1145
-3.3c=-300.3
c=91
solve for a
c+a=149
91+a=149
a=58
Check answer:
6.4c+9.7a=1145
6.4(91)+9.7(58)=1145
582.40+562.60=1145
1145=1145
