<span>n=toms weight
(n-30)=jims weight
and together they weigh 210
so it would be (n - 30) + n = 210</span><span>

Answer:
Step-by-step explanation:
- <em>Sum of exterior angles of any polygon is 360°</em>
<h3>Exercise 8</h3>
<u>Sum of given angles:</u>
- 2x + 60° + 64° + 36° + 48° = 360°
- 2x + 208° = 360°
- 2x = 360° - 208°
- 2x = 152°
- x = 76°
<h3>Exercise 9</h3>
<u>Sum of given angles:</u>
- x + 90° + 109°+ 73° = 360°
- x + 272° = 360°
- x = 360° - 272°
- x = 88°
Answer:
x=5
Step-by-step explanation:
4x+8=2x+3x+3
2x+3x=5x
4x+8=5x+3
-4x
8=1x+3
-3
5=1x
5/1
x=5
= 3(4a^2 + 4a - 3) - 4a^2 + 28
= 12a^2 + 12a - 9 - 4a^2 + 28
= 8a^2 + 12a + 19
= 4a(2a + 3) + 19
