The width of a rectangle is 9 inches more than 5 times the length. If x represents the length, write an algebraic expression in terms of x that represents the perimeter of the rectangle. Simplify the expression.

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.

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
