Answer:
The expression that represents the perimeter of the rectangle is "12*x + 18", where "x" is the length of the rectangle.
Step-by-step explanation:
In order to solve this question we were given an expression that relates both dimensions of the rectangle. This expression in a mathematical form where "x" is the length and "y" is the width is shown bellow:
y = 9 + 5*x
The perimeter of a rectangle is given by:
perimeter = 2*length + 2*width
perimeter = 2*x + 2*(9+5*x)
perimeter = 2*x + 18 + 10*x
perimeter = 12*x + 18
The expression that represents the perimeter of the rectangle is "12*x + 18", where "x" is the length of the rectangle.
You have to make the denominators (bottom numbers) the same via multiplication, it's best to do it to the first number they meet at. that would be fifteen (15)
5×3=15
3×5=15
you then have to multiply the numerators by the respective numbers.
2×3=6
1×5=5
you then subtract the numerators normally
6-5=1
slap back on the denominator
1/15
there's your answer.
(the number you multiply them by isn't the other denominator, it just happens to be the denominators for this equation)
Answer:
2167.7 sq yds
Step-by-step explanation:
SA(cone) = πr² + πrs ('s' = slant height)
= π(15)² + π(15)(31)
= 225π + 465π
= 690π
= 2167.7
