Your answer would be option (1) -3x² - 18x + 19.
To find this we need to substitute in the G and F expressions into G - 3F and see what the outcome is, as this will give us the answer.
First I’m going to multiply the F expression, 2x² + 6x - 5, by 3:
3 × (2x² + 6x - 5) = 3(2x²) + 3(6x) - 3(5) = 6x² + 18x - 15.
Now we need to subtract this expression from G, which is 3x² + 4, which I will do by term:
3x² - 6x² = -3x²
0x - 18x = -18x
4 - -15 = 19
So therefore overall your answer is -3x² - 18x + 19.
I hope this helps! Let me know if you have any questions :)
<h2>
It is an obtuse angle.</h2>
Step-by-step explanation:
Obtuse: An obtuse angle is an angle more than 
but less than 
.

,
etc.
Acute : An acute angle is an angle less than
Example :

etc.
Straight : A straight angle is .
Right: A right angle is .
Since the angle is more than but less than . So, it is an obtuse angle.
Answer:
420:8
Step-by-step explanation:
1a. Split the larger piece(1/3) into half to show the two pieces
1b. Both are 3/6 or 1/2
2a. It shows 1/2 +1/4
2b.cut it so there are 3 1/4 pieces, so cut the 1/2 piece horizontally in the middle
2c. 2/4 + 1/4 = 3/4. 1/2 + 1/4 = 3/4
