Answer:
Step-by-step explanation:
<u>See the steps below:</u>
- 3x² + 20x - 7 =
- 3x² + 21x - x - 7 =
- 3x(x + 7) - (x + 7) =
- (x + 7)(3x - 1)
Your answer would be 19/20 :)
Yea, sure thing...
So like, in a quadrilateral the sum of its angles will form 360°.
So,
(2x - 16)° + 2x° + x° + (x + 10)° = 360°
2x - 16 + 2x + x + x + 10 = 360
2x + 2x + x + x - 16 + 10 = 360
6x - 6 = 360
6x = 360 + 6
6x = 366
x = 366 ÷ 6
x = <u>6</u><u>1</u><u>.</u>
m<R = 2x° = 2 × 61 = <em><u>1</u></em><em><u>2</u></em><em><u>2</u></em><em><u>°</u></em><em><u>.</u></em>
Hope it helps ya mate :))
