No would arrive before yes
The first one is C because on a coordinate plane is you count the number of spaces between them it’s 7 side to side( horizontal) and the second one is quadrant 2 because when reflecting across the y axis you move over the y axis which is why it’s quadrant 2. Hope this helps!
Step-by-step explanation:
(2a+3b)(4a²-6ab+9b²
(2a+3b){(2a)²-2a×3b+(3b)²}
Because (a³+b³)=(a+b)(a²-ab+b²)
Therefore,
(2a+3b){(2a)²-2a×3b+(3b)²}
=(2a)³+(3b)³
By substituting the values , we get
- (2a)³+(3b)³
- (2×3)³+(3×(-5))³
- 6³+(-15)³
- 216+(-3375)
- 216-3375
- -3159
Well first of all, we know right away that no rounding will be necessary, because the square of a whole number is another whole number. The square of 110 is 12,100 .
