-(-2-5x)+(-2)=18
2+5x-2=18
5x=18
x=18/5=3.6
Answer:
Step-by-step explanation:
(a+b)^2=a^(2)+2ab+b^(2)
(a-b)^2=a^(2)-2ab+b^(2)
13)
(x+2)^(2)-(x-1)^2
x^(2)+4x+4-(x^(2)-2x+1)
x^(2)+4x+4-x^(2)+2x-1
6x+3
15)
(x+5)^(2)-(x+1)^2
x^(2)+10x+25-(x^(2)+2x+1)
x^(2)+10x+25-x^(2)-2x-1
8x+24
It would be 15x/9x
Hope this helps
Let's write the equation with formula:-

Where,
- x1 is -1 and y1 is 4 and m is 3





<em>Thus, The correct choice is option C!!~</em>
