Answer:
−13x^3+2y
Step-by-step explanation:
−4x3+2y−9x3
=−4x3+2y+−9x3
=−4x3+2y+−9x3
=(−4x3+−9x3)+(2y)
=−13x3+2y
Answer:
Because it bears an equal sign
Expressions don't have a definite solution to the problem.
Answer:
The smallest number that is divisible by 1,2,3,4,5,6,7,8,9 and 10 is 2,520.
Step-by-step explanation:
2520/1 = 2520
2520/2 = 1260
2520/3 = 840
2520/4 = 630
2520/5 = 504
2520/6 = 420
2520/7 = 360
2520/8 = 315
2520/9 = 280
2520/10 = 252
Answer:
2
Step-by-step explanation:
A polygon has the following coordinates: A(3,1), B(5,3), C(2,5), D(-1,5), E(-4,3), F(-2,1). Find the length of DC.

To find the length of a line given two points, we are going to use the distance formula, which is defined below:
( and are the two points)
The points in this problem are (2, 5) and (-1, 5). We can find the distance of DC by substituting these values into the distance formula and simplifying, as shown below:
- Substitute values into formula
- Combine like terms and then simplify to 0
- Compute
- Compute
The length of DC is 3.
