Answer:
x <u>></u> -3
Step-by-step explanation:
- 4x - 10 <u><</u> 2
+ 10 <u><</u> + 10
<u>- 4x < 12</u>
-4 -4
I think the sign flips because the negative sign is w/the X.... If it doesn't, sorry 4 being wrong...
B
Given - Two angles measures 2x and 3x
To find - size of 3x
Solution -
2x + 3x = 360° ( Make reflex angle )
5x = 360°
x = 360/5
x = 72°
3x = 3 * 72 = 216°
-7x²=185-10
-7x²=175
x²=-25
x=±√-25
60
240/4
