First you want to write 7x as a sum or difference: 15x-8x
Now, the expression would look like this: 10x^2+15x-8x-12
Next, factor out the 5x and -4 from the expression: 5x(2x+3)-4(2x+3)
Now, factor out the 2x+3 from the expression and you have your answer:
(2x+3)(5x-4)

A washer and dryer cost 1003 combined the washer cost 53 more than dryer what’s the cost of dryer

NeX [460]

Answer:

475

Step-by-step explanation:

Let's call the dryer price is x

Then, the price for the washer is 53 more than the dryer, it would be: x+53

Total price of washer and dryer = 1003

We get the equation:

x+(x+53) = 1003

2x + 53 = 1003

2x + 53 - 53 = 1003 - 53

2x = 950

x = 475

The dryer price is 475

Extra: you can find the cost of the washer by using x+53 = 475+53 = 528
