Answer:
triangle
Step-by-step explanation:
M=change in y/change in x
Finding gradient of the orginal line
=3+1/0-3
=-4/3
Since parallel lines are equal the other line would be -4/3 (gradient)
Sub (-3;2) into y=mx+c
2=-4/3 (-3)+c
2=4+5
2-4=c
-2 = c
Therefore sub all your info and you get y= -4/3x-2
After staring at this for a few seconds, I think the equation
![-5\sqrt{10}\cdot\sqrt{15}=[1]\sqrt{[2]}](https://tex.z-dn.net/?f=-5%5Csqrt%7B10%7D%5Ccdot%5Csqrt%7B15%7D%3D%5B1%5D%5Csqrt%7B%5B2%5D%7D)
is asking you to simplify the left hand side so that it has a form matching the right hand side, and [1] and [2] are placeholders. My guess is that they're supposed to be integers.
Notice that
![\sqrt{10}=\sqrt{5\cdot2}=\sqrt5\cdot\sqrt2](https://tex.z-dn.net/?f=%5Csqrt%7B10%7D%3D%5Csqrt%7B5%5Ccdot2%7D%3D%5Csqrt5%5Ccdot%5Csqrt2)
![\sqrt{15}=\sqrt{5\cdot3}=\sqrt5\cdot\sqrt3](https://tex.z-dn.net/?f=%5Csqrt%7B15%7D%3D%5Csqrt%7B5%5Ccdot3%7D%3D%5Csqrt5%5Ccdot%5Csqrt3)
![\implies\sqrt{10}\cdot\sqrt{15}=(\sqrt5)^2\cdot\sqrt2\cdot\sqrt3=5\sqrt{2\cdot3}=5\sqrt6](https://tex.z-dn.net/?f=%5Cimplies%5Csqrt%7B10%7D%5Ccdot%5Csqrt%7B15%7D%3D%28%5Csqrt5%29%5E2%5Ccdot%5Csqrt2%5Ccdot%5Csqrt3%3D5%5Csqrt%7B2%5Ccdot3%7D%3D5%5Csqrt6)
Then multiplying by -5, we have
![-5\sqrt{10}\cdot\sqrt{15}=-25\sqrt6](https://tex.z-dn.net/?f=-5%5Csqrt%7B10%7D%5Ccdot%5Csqrt%7B15%7D%3D-25%5Csqrt6)
so I believe [1] = -25, and [2] = 6.
Answer:
c

Answer:
14ft
Step-by-step explanation:
Since the scale is 2in : 7ft, so you would do 7x2 which gets you to 14.
(You would do 7x2 because 4 in/2 in = 2in, that's where the 2 comes from, and 7 because 7ft is part of the scale.)
Hope this helps :D
