Consider the width as x.
Width = x
Length = 3x-4
2(3x-4)+2(x) = 64
6x-8+2x = 64
8x-8 = 64
8x = 72
x = 9
Width = 9 meters
Length = 23 meters

How many more equal angles does a square have than a rectangle?

leva [86]

A rectangle, is a quadrilateral with all angles at 90°.

a square is a quadrilateral with all equal sides, and right-angles all around.

now, the rectangle as well as the square, have all right-angles, the only difference is that the square has all equal-length sides, whilst a rectangle can have pairs of sides that vary in length.

What number must be added to the expression below to complete the<br> square?<br> x² - 18x

kiruha [24]

Answer:

$\boxed {\boxed {\sf 81}}$

Step-by-step explanation:

The standard form of a quadratic is:

$ax^2+bx+c$

To complete the square, the a (leading coefficient) must be 1 and there can only be terms with variables on one side.

The expression given:

$x^2-18x$

follows these rules. Next, we divide the b (linear coefficient) by 2, then square it. Basically:

$(\frac{b}{2})^2$

The b in the expression is -18.

$(\frac{-18}{2})^2$

$(-9)^2= -9*-9= 81$

This is the number that is added.
