Answer: 74
Step-by-step explanation:
Substitute x=6 into the expression
(x+4) . 2^3 -6
Add the numbers
(6+4) . 2^3- 6
10 x 2^3 -6
Evaluate the power
10 x 2^3 -6
10 x 8-6
Multiply the numbers
10 x 8-6
80-6
Subtract the numbers
80-6
74
Apologies, but there is no map...?
form 2 equations
length=x
width=y
the equations are:
2(x+y)=82, because 82 would the the perimeter which is 2(l+w)
x=y+9
Now use substitution and you'll get y=16. Then plug in 16 and you'll get x=25. so the length is 25 and the width is 16.
Therefore the dimensions would be 25 by 16. Notice that the length, 25, is 9 greater than the width, 16. Also notice that a perimeter of a rectangle with length 25 and width 16 is 82 ( 2(25+16)=2(41) = 82))
