<span>The perimeter of a rectangle is:
P = 2(l + w)
So we have:
P = 2(l + x)
This is one of our expressions.
It says the length is 3 times the width.
So we have 3 * x or 3x.
We can write:
l = 3x
Now plug this into the formula:
P = 2(l + x)
Plug in '3x' for 'l'</span>
Find the area of each face and add them all together, or since a cube has 6 faces, you can multiply the area of one face by 6.
Answer:
Step-by-step explanation:
The answer is 7-1=6
Since 1 raised to the fourth is equal to 1
Plz mark it as brainliest:)
-1/5 + (-3/4)
= -1/5 - 3/4
= -4/20 - 15/20
= -19/20
9x + 2 + 8x + 1 = 17x + 3
The answer is 180 - 17x + 3 I'm pretty sure
