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)

Solve 2(1 – x) > 2x.
Fantom [35]

First you must distribute the 2 to the numbers inside the parentheses, which would be 1 and -x...

(2 * 1) + (2 * -x) > 2x

2 + (-2x) > 2x

2 - 2x >2x

Add 2x to both sides (what you do on one side you must do to the other). Since 2x is being subtracted, addition (the opposite of subtraction) will cancel it out (make it zero) from the left side and bring it over to the right side.

2 - 2x + 2x > 2x + 2x

2 + 0 > 4x

2 > 4x

Next divide 4 to both sides to finish isolating x. Since 4 is being multiplied by x, division (the opposite of multiplication) will cancel 4 out (in this case it will make 4 one) from the right side and bring it over to the left side.

2/4 > 4x / 4

1/2 > x

or

x < 1/2

Hope this helped!

How can you express the properties of operations to evaluate this expression 18 + 4(28)
Akimi4 [234]

Answer:

I don't know if I'm understanding your question correctly. But I'll try...

In this problem you need to remember PEMDAS!

Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

18 + 4(28)     -First you would multiply 4 by 28 since the 28 is in parentheses.

18 + 112        -Now you would add to find your answer

= 130

I hope this helps!
