Answer:
<h2>L=8in</h2><h2>W=5in</h2>
Step-by-step explanation:
Step one:
given data
we are told that the border/perimeter of the yellow ribbon is 26in
let the width be x
W=x
and the lenght
L=x+3
Step two:
Required
The expression for the perimeter to find the dimensions of the yellow ribbon given the above condition.
we know that the perimeter of a rectangle is given as
P=2L+2W
26=2(x+3)+2x---------This is the expression required
26=2x+6+2x
26=4x+6
26-6=4x
20=4x
divide both sides by 4
x=20/4
x=5in
The width is 5in
The length is
L=x+3
L=5+3
L=8in
Answer:
C. 6*9^3 + 1*9^2 + 1*9^1 + 5*9^0
Step-by-step explanation:
In base 9, each digit to the left represents a power of 9.
The rightmost digit represents 9^0, the next digit to the left represents 9^1, the next digit to the left represents 9^2, and the 4th digit represents 9^3.
Answer: C. 6*9^3 + 1*9^2 + 1*9^1 + 5*9^0
