3*4*3-2*4^2 = 36-32 = 4
Good evening my friend.
The first thing we need to thing about is to replace each values by the number that they give for them.
So let's start by replacing 4 every where we see x and 3 everywhere there is y
3(4)(3) - 2(4)²
36 - 2(16)
36- 32
= 4
I hope that's help :)

You can call it a constant proportionality table because it is used to find the constant of proportionality and proportional relationships. (I am not really sure)
Answer:
x = 15/p
Step-by-step explanation:
4(px + 1) = 64
4px + 4 = 64
-4 -4
4px/p = 60/p
4x/4 = 60/p/4
x = 15/p
Step-by-step explanation:
m1.m2 = -1
18.m2 = -1
m2 = -1/18
formula = y - y1 = m2 ( x - x1)
y - (-5) = -1/18 ( x -1)
y + 5= -1x/18 +1/18
y = - 1 x / 1 8 - 8 9 / 1 8
I can't see what expressions you had posted. Maybe you didn't typed it out, but 649*36=23364
