Answer:

It is 28 miles. It is much more simple than you are making it out to be in your head. Draw out the picture with 7 marks on a line. The first 3 marks were traveled Friday. After Friday, there are 4 marks left. On Saturday, 2 of those 4 remaining marks are traveled. On Sunday, the last two marks are traveled. The last two marks are 8 miles together, meaning that each mark is 4 miles a piece. Therefore, 7 times 8 is 28 miles.

Match the reasons with the statements. GIVEN: x2 + 6x + 2x + 12 = 0 TO PROVE: x = -6 or x = -2 1. x2 + 6x + 2x + 12 = 0 Subtract

mestny [16]

Given: $x^2 + 6x + 2x + 12 = 0.$

1. Combining like terms (here terms 6x and 2x both contain x, then we can combine them):

$x^2+(6x+2x)+12=0,\\\\x^2+8x+12=0.$

2. Distributive postulate:

$x^2+8x+12=(x+6)(x+2).$

The equation is

$(x+6)(x+2)=0.$

3. Zero product postulate (zero product postulate state that if a product of two factors is equal to zero, then first factor is equal to zero or second factor is equal to zero):

$x+6=0 \text{ or } x+2=0.$
