Answer:
x = 5/-8
Step-by-step explanation:
4x = 12x + 5
4x - 12x = 5
-8x = 5
x = 5/-8
Answer:
72
Step-by-step explanation:
You can find ten percent of 180 pretty easily, it is 18 (divide by 10) then multiply by 4 to get 40%.
The perimeter of a rectangle is P=2l+2w where l is the length and w is the width.
Plug in values of l and w in:
P=2(x+8)+2(x-1)
P=2x+16+2x-2
P=4x+14
So the perimeter of the rectangle is 4x+14 units
Hope this helped!
Do you know how to simplify, let's say for example, x⁵/x² ?
When the bases are the same, you can just subtract the exponent in
the denominator from the exponent in the numerator. So x⁵/x² = x³ .
Now look at x⁷/x⁷ . From that same handy tip, x⁷/x⁷ = x⁰ .
BUT ... any fraction with the same number on top and bottom
is equal to ' 1 '. So x⁰ = 1 , no matter what 'x' happens to be.
Does that do anything for you ?
