Which statement about the equation below is true? x2 − 8x + 15 = 0 A. One root is less than zero, and the other root is greater than zero.
B. One root is zero, and the other root is greater than zero.
C. The sum of the roots is 15.
D. Both roots are greater than zero.

both roots are greater than zero

Step-by-step explanation:

If this is factored, you can find the roots.

(x-3)(x-5)=0

Set each factor equal to zero and solve.

x-3=0

x=3

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
