Answer:

14x² - 25x + 6

Step-by-step explanation:

The area of a rectangle is denoted by: A = lw, where l is the length and w is the width.

Here, the length is 7x - 2 and the width is 2x - 3, so plug these in:

A = lw

A = (7x - 2)(2x - 3)

We have to use FOIL (first, outer, inner, last):

(7x - 2)(2x - 3) = (7x)(2x) + (7x)(-3) + (-2)(2x) + (-2)(-3) = 14x² -21x - 4x + 6

The answer is thus 14x² - 25x + 6.

Answer:

14(x^2) - 25x + 6

Step-by-step explanation:

Area of rectangle = length * width

length = 7x - 2

width = 2x - 3

(7x - 2) (2x - 3) =

14(x^2) - 25x + 6

Prove if a and b are integers, prove that if a is even and b is even then a+b is even

jeka57 [31]

Answer:

Let a and b integers and suppose that are even numbers. Then, exist integers k and m such that $a=2k$ and $b=2m$ .

Then,

$a+b=2k+2m=2(k+m)=2n$

Since, k and m are integers then n=k+m is an integer. Then, since a + b is of the form 2 by an integer n, then a + b is an even number.
