N²+20n+100 = (n+10)(n+10)
Yes is it a perfect square trinomial
Answer:
y=8x-69
Step-by-step explanation:
you would use the equation y-y1 = m (x - x1)
plug in m = 8 , y1 = 3, x1 = 9
now you have y - 3 = 8 (x-9)
distribute 8 --> y-3 = 8x - 72
add three to both sides to get y = 8x - 69
Answer:
- 3*2=
![\sf{\pink{\dfrac{4}{5}}}](https://tex.z-dn.net/?f=%5Csf%7B%5Cpink%7B%5Cdfrac%7B4%7D%7B5%7D%7D%7D)
Step-by-step explanation:
<u>Given</u><u> </u><u>that</u><u>,</u><u> </u>
x*y=![\dfrac{(2x-y)}{(x+y}](https://tex.z-dn.net/?f=%5Cdfrac%7B%282x-y%29%7D%7B%28x%2By%7D)
<h3>
<u>SO</u><u>,</u><u> </u></h3>
3*2=
