A. Area of a square= side length squared
=> A= (x-3)^2
= x^2-6x+9
b. Area of rectangle= larger side length* smaller side length
=> A= x(x-5)
= x^2-5x
c. If both areas equal then expressions for areas equal as well.
x^2-5x= x^2-6x+9
=>x=9

The formula A = (1/2)bh represents the area of a triangle where A represents the area, b is the base of the triangle and h is th

gizmo_the_mogwai [7]

Answer:

$b=\frac{2A}h$

Step-by-step explanation:

You first multiply both sides by 2 (if two quantities are the same, double the quantities will be the same).

$2A = bh$

Then, as long as the height of the triangle isn't zero, you divide both sides by h

$\frac{2A}h = b$ Reading right to left gives you the result

AlekseyPX

Answer:

Her father is 81 inches tall.

Step-by-step explanation:

She is 2/3 as tall as her father so we divide her height by 2. 54/2=27 and then we multiply 27 by three to get 81 inches.
