So since the length is 4+w. Then the perimeter 2(4+w) + 2w >= 48.
so, 8+2w+2w>=48.
8+4w>=48
4w>=40
w>=10
so, the width must be at least 10. And the smallest dimensions can be 10 x 14.
Answer:
(x, y) =(2,-3)
Step-by-step explanation:
4x+3y=-1
3x-9y=33 /:3
4x+3y=-1.....(1)
x-3y=11... (2)
(1)+(2): 5x=10
x-3y=11
x=10/5
x-3y=11
x=2
2-3y=11
x=2
-3y=11-2
x=2
-3y=9
x=2
y=9/(-3)
x=2
y=-3
(x,y)=(2,-3)
B it is between 30 and 60
Answer:
Multiply both sides of the equation

Answer:
8w^2 I don't know why it is not on here, but I put it in an algebra calculator and everything. Good luck. :)
Step-by-step explanation:
Simply the radicals by multiplying and taking square roots.
2![\sqrt[4]{8w^3}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B8w%5E3%7D)
* ![\sqrt[4]{32w^5}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B32w%5E5%7D)
= 2 *2w![\sqrt[4]{2w}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2w%7D)
= 4w![\sqrt[4]{16w^4}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B16w%5E4%7D)
=4w(2w)
=
