Question

Please. I really need help in Algebra I. THE PICTURE GOES TO THE THIRD PROBLEM.

Answer 1

Answer:

1) 2x^2 -8x

2) 18x^2 -45x

Step-by-step explanation:

These problems make use of the distributive property. It tells you how you can use or eliminate parentheses as you may need.

  a(b + c) = ab + ac . . . . . . . the outside factor multiplies each inside term

Of course, the usual rules of multiplication of positive and negative numbers apply. If the number of minus signs in a product is odd, the result is negative; otherwise the result is positive.

1. 2x(x -4) = (2x)(x) + (2x)(-4) = 2x^2 -8x

2. -9x(5 -2x) = (-9x)(5) + (-9x)(-2x) = -45x +18x^2 = 18x^2 -45x

3. She used the algebra tiles correctly.

• The headers correctly represent -2x-2 and 2x-1
• Each product has the correct sign (-- = +, -+ or +- = -)
• Each product has the correct power of x
