Hey there! :D
Plug in x for 2.
4x= 4(2)
x^4= (2^4)
Evaluate.
4x= 8 2^4= 16
Now, subtract the difference.
16-8= 4
The difference is 4.
I hope this helps!

Just set m=36 and n=72
substitute in the original function
133
Solution
x2 -3xy
=(-7)2- 3x(-7) x 4
=49 + 21 x 4
=49 + 84
=133
Note: I put 2 instead of the “mini 2” or squared cuz I cant copy and paste it lol
Answer:
Algebra
Step-by-step explanation:
(+) it's the same thing btw6x -8 = 4x
(collect like terms) meaning the numbers with x go over the " = " sign
making it = -8 = 4x -6x
the signs change when it crosses over so it becomes that
-8 = -2x
-8 ÷ -2 = 4 (cause - ÷ by - is + )
Answer:
width=11/2
length=8
Step-by-step explanation:
44=(2w-3) x w <em>area for a rectangle (44) = the length (2w-3) times the width (w)</em>
44=2w^2 - 3w <em>distribute</em>
2w^2-3w-44 = 0 <em>subtract 44 from both sides</em>
(w+4)(2w-11) <em>factor</em>
width=11/2
(11/2 x 2) - 3
length = 8
