Let the width be x cm.
Then length=3x-4 cm.
Its perimeter is 64 cm.
We know that perimeter of a rectangle= 2(length+width)
So,
2(3x-4+x)=64
6x-8+2x=64
6x+2x=64+8
8x=72
x=9
Therefore,
length=(3×9-4)cm=(27-4)cm=23 cm.
Width=9 cm.
Answer: The y-intercept is -8
Step-by-step explanation:
It's simple to understand once you memorize the slope intercept formula!
y=mx+b
m stands for the slope which is rise/run
The b is the y-intercept, which is the answer you are looking for! the y-intercept is where the line crosses the y-axis!
Answer:
Option (A).
Step-by-step explanation:
is a mixed fraction and can be written as,
[Combination of a whole number and a fraction]
When we multiply this mixed fraction by 7,

[Distributive property → a(b + c) = a×b + a×c]





Therefore,
will be the answer.
Option (A) will be the correct option.

But x must be a natural number, so the answer is

.
