The equation x^2+ (k - 3)x + (3 - 2k) = 0, where k is a constant, has two distinct real roots.

Lisa [10]

Step-by-step explanation:

For quadratic equation ax^2 + bx + c = 0 to have two distinct real roots,

b^2 - 4ac must be positive.

b^2 - 4ac > 0

(k - 3)^2 - 4(3 - 2k) > 0

k^2 - 6k + 9 - 12 + 8k > 0

k^2 + 2k - 3 > 0

Maya wrote the expression 3+5+4.5 to represent the total distance that she traveled. Which statement best describes Maya’s expre

harina [27]

<u>Answer:</u>

The statement, Maya’s expression will generate the correct sum because of the associative property will describe the best.

<u>Solution: </u>

Maya’s expression will generate the correct sum because of the associative property.

Maya wrote the expression $3+5+4.5$

As per commutative property of addition if we change the order still the sum will be same, which means $(a + b) = (b + a)$

Here also, $(3 + 5) + 4.5 = 8+4.5 = 12.5$

Again $3 + (5+4.5) = 3+9.5 = 12.5$

As both the results are same, hence this is meeting the commutative property of addition.
