i.e., A. 4(3) and B.
Step-by-step explanation:
Like radicals are similar to like terms.
For example,
x, 2x, -10x, , 7.3x are like terms.
are some more examples of like terms.
Similarly, like radicals are:
etc.
Hence, from the given options, like radicals to are:
A. and B.

These aren't too hard -- you should really try to do them yourself.
The upper triangle has base 2+2=4 and height 3.2. The lower one has base 4 and height 4. Of course the area of a triangle half base times height.
Area = (1/2) 4(3.2) + (1/2)(4)(4) = 2(7.2) = 14.4
Answer: 14.4 sq ft
If they drove a total of 5,300 miles in 2 days, and on the second day they drove 10 more miles then the 1st day.
5,300 ÷ 2 = 2,650
they drove 10 miles less on the first day
2,650 - 10 = 2,640
They drove 2,640 miles on the first day.
Hope this helps. :)
Answer:
-4
Step-by-step explanation:
9(2x + 1) < 9x – 18
Divide each side by 9
9/9(2x + 1) < 9x/9 – 18/9
2x+1 < x-2
Subtract x from each side
2x+1-x < x-2-x
x+1 < -2
Subtract 1 from each side
x+1-1 < -2-1
x < -3
The only value less than -3 is -4
