The length of a rectangle is (x-8) units, and its width is(x+11) units. What is an expression for this.

Ipatiy [6.2K]

Answer:

(x²+3x-88) square units

Step-by-step explanation:

Area of a rectangle = Length × Width

Given

length of a rectangle is (x-8)units

Its width is (x+11) units.

Required

Expression for the area of the rectangle

Substituting the given function into the formula.

Area of the rectangle = (x-8)(x+11)

Area of the rectangle = x(x)+11x-8x-88

Area of the rectangle = x²+3x-88

Hence the expression that represents the area of the rectangle is x²+3x-88 units²

Use the commutative property to identify which expression is equal to (3+5)(x)8<br> x means times

klasskru [66]

Given expression : $(3+5)\times8$

According to the Commutative property of Addition

For any $a,b$ :

$a+b=b+a$

Therefore, the given is equal to: $(3+5)\times8=(5+3)\times8$

Also, by the Commutative property of Multiplication

For any $a,b$ :

$a \times b=b \times a$

Therefore, the given is equal to: $(3+5)\times8=8\times(3+5)$
