Answer:
C
Step-by-step explanation:
We need to first rewrite the equation the proper way.
(-2x+4x²+5)-(x²+3x)
We need to distribute the negative thought the 2nd set of parenthesis.
-2x+4x²+5-x²-3x
combine the same terms
3x²-5x+5
Answer:
160 unit^2.
Step-by-step explanation:
Area = xy/2 where x and y are the length of the diagonals, so here:
Area = (16*20)/2
= 320/2
= 160.
In interval notation, square brackets indicate that a function can take on that value (or uses a less/greater than or equal to sign). Parenthesis indicate that a function cannot take on that value (or uses a less/greater than sign).
In the case of the given set, both inequality signs are less/greater than or equal to. This indicates to us that we will use brackets in both instances because the set can be equal to -2 and 2.
Answer: [-2,2]
Answer Choice: D
Hope this helps!
The answer is 34x67 because if you follow PEMDAS you do the () first so 58+9 equal 67 and then you multiply 34x67 which will equal 2,278
Hope this helps :)
