2x multiplies to all numbers:
2x x 8x3 = 16x4
2x x 6x2 = 12x3
2x x -10x = -20x2
Answer: 16x4 + 12x³ - 20x²
Hope this helps :)
Answer: B
Step-by-step explanation:
To find the result of the dilation, multiply each x and y coordinate by the scale factor, which in this case, is 1.5. I started out with the coordinate P, which had an original coordinate of (-2,1). In this case, I multiplied -2 by 1.5, and 1 by 1.5 to get (-3, 1.5). Since this is multiple choice, the only one with P as (-3, 1.5) is B, so we don't have to check the others.
A)
Earlier, The length of the angelfish = 
inches
Now, the length of angelfish = 
inches
We have to determine the grown length of angelfish
= -
= 
LCM of '2' and '3' is '6',
= 
= 
inch
Therefore, the angelfish has grown by inch.
B)
We have to determine the increased length of angelfish in feet.
Since 
foot
So, 
= 0.069 foot.

but this would have to be simplified also
