Answer:
★ The two factors of the number 221 are 13 and 17.
A factor refers to a whole number, which fits evenly into another whole number. Thus, factors are the numbers, which we multiply together to get another number. The two numbers that can be multiply together to get 221 are 13 and 17.

Answer:
2x + 5y = -15
Step-by-step explanation:
First, find the <em>Rate of change</em> [<em>Slope</em>]:
-y₁ + y₂\-x₁ + x₂ = m
1 - 7\5 + 10 = -⅖
Apply the Point-Slope Formula, <em>y - y₁ = m(x - x₁)</em>, since we are given points. It does not matter which one you choose. NOTE: All negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY careful inserting the coordinates into the formula with their CORRECT signs:
y + 7 = -⅖(x - 10)
y + 7 = -⅖x + 4
- 7 - 7
_________________
y = -⅖x - 3 >> Line in <em>Slope-Intercept Form</em>
Here it is in <em>Standard Form</em>:
y = -⅖x - 3
+⅖x +⅖x
____________
⅖x + y = -3 [We do not want fractions in our Standard Equations, so multiply by the denominator to get rid of it.]
5[⅖x + y = -3]
2x + 5y = -15 >> Line in <em>Standard Form</em>
__________________________________________________________
y + 1 = -⅖(x + 5)
y + 1 = -⅖x - 2
- 1 - 1
________________
y = -⅖x - 3 Line in <em>Slope-Intercept</em><em> </em><em>Form</em><em> </em>
y = -⅖x - 3
+⅖x +⅖x
___________
⅖x + y = -3 [We do not want fractions in our Standard Equations, so multiply by the denominator to get rid of it.]
5[⅖x + y = -3]
2x + 5y = -15 >> Line in <em>Standard Form</em>
** You see? I told you it did not matter which ordered pair you choose because you will always get the EXACT SAME RESULT.

1 m = 1000 mm so due to that 0,13 m = 1000 * 0,13m = 130mm
