Find the area of the rectangle below multiplying its length and width (5x-4)(2x-5)
Serhud [2]
Use the FOIL method to multiply these terms.  Multiply the first, outside, inside, and last terms:


(5x - 4)(2x - 5)

(5x)(2x) + (5x)(-5) + (-4)(2x) + (-4)(-5)

10x² - 25x - 8x + 20

10x² - 33x + 20


The area of the rectangle should be 10x² - 33x + 20.

Brilliant_brown [7]

Answer:

98.

Step-by-step explanation:

  • Parenthesis
  • Exponents
  • Multiplication
  • Division
  • Addition
  • Subtraction

You have to do it in order so you can get the correct answer. Do the problem in the parenthesis first. 6 ÷ 3 = 2.

It should look like this:

7² x 2.

Then, do your exponents. 7² is just basically 7 x 7. It equals 49.

Now, it should look like this:

49 x 2. Multiply 49 x 2, and your answer should be 98.
