(2x-5)^2
show your work or no points

(2x - 5)^2 can be expressed as (2x - 5) * (2x - 5) or simply just (2x - 5)(2x - 5)

Then multiply each term in the first parentheses against the all the other terms in the second parentheses.

(2x - 5)(2x - 5) = 4x^2 -10x - 10x + 25

Combine like terms.

4x^2 -10x - 10x + 25 = 4x^2 - 20x + 25

So, 4x^2 - 20x + 25 is the answer.

(2x-5)^2= 4x^2-20x+25

Step 1: (2x-5)(2x-5).
Step 2: 2x times 2x is 4x^2.
Step 3: -5 times 2x is -10x.
Step 4: 2x times -5 is -10x.
Step 5: -5 times -5 is 25.
Step 6: You will have 4x^2-10x-10x+25.
Step 7: 4x^2-20x+25.
4x^2-20x+25 is your answer.

550

Step-by-step explanation:

Divide the $100 by 12 = 8.33

Multiply 8.33 * 66 = 550
