Dimensions of rectangle are:
Length = 26 cm
Width = 9 cm
Step-by-step explanation:
Perimeter of rectangle = 70 cm
Width= x
Length = 2x+8
We need to find the value of length and width of rectangle.
The formula used is:

Putting values:

So, Value of Width = x = 9 cm
Value of Length = 2x+8 = 2(9)+8 = 18+8=26 cm
So Dimensions of rectangle are:
Length = 26 cm
Width = 9 cm

its A
Step-by-step explanation:
Answer:
P=2x+2y+14
Step-by-step explanation:
Perimeter (P)of a rectangle = 2( l+b)
where l is the length and b is the width of the rectangle .
Here, l= x+8
and, b= y-1
so, P = 2{(x+8)+(y-1)}
= 2( x+8+y-1)
= 2(x+y+7)
=2x+2y+14
If you graph out y = x^2 - 1, you'll see that it is a curved parabola. It is not a straight line. So visually this shows the equation is not linear. It's considered nonlinear.
Algebraically, the given equation does not fit the form y = mx+b which is slope intercept form. So this is more confirmation that we do not have a linear function.
