Answer:

4x² - 20x + 20

Step-by-step explanation:

(a - b)² = a² - 2ab + b²

a = 2x  ; b = 5

(2x- 5)² = (2x)² - 2*2x*5 + 5²  {(2x)² = 2x * 2x = 4x²}

           = 4x² - 20x + 25

An equation is shown below: 8x + 2(x – 7) = 7x + 3x – 14 Part A: Solve the equation and write the number of solutions. Show all
marta [7]

Answer:

  1. Infinitely Many
  2. Distributive Property

Step-by-step explanation:

8x + 2(x - 7) = 7x + 3x - 14

8x + 2x - 14 = 7x + 3x - 14                 Distributive property.

10x - 14 = 10x - 14                              Combine the like terms.

-14 = -14                                             Subtraction.

0 = 0                                                  Addition.

Since the statement 0 = 0 is true regardless of the value of x, there is infinitely many solutions.

You make $7 an hour. You work 40 hours a week for a year. (52 weeks) How much will you make?
valina [46]

If you made $7 an hour and worked for 40 hours, every day for a year, you would make $14,560 a year and about $1,213.33 a month.

Because 7 x 40 = 280 (which is how much money you make a week.)

And 280 x 52 = 14,560 (because you would work for 52 weeks).

I hope this helped! Good luck and have a great night!
