Factor the following trinomial. x^2-15x+56

Step 1: The trinomial factors as x^+bx+c=(x+p)(x+q), where p+q=b and p*q=c. Fill in the following table with all of the possible values of p and q, using the fact that their product is the constant term, c=56

Step 2: Which factors for p and q add to equal the coefficient of the term x-term (-15) in the trinomial.

Step 3: Using the factors from Step 2, write the trinomial x^2-15x+56 in the factored form.

The final cost of a sale is determined by multiplying the price on the tag by 75%. which best describes the function that represents the situation?

The length of a shadow of the building is 36m. the length of the pole, which is perpendicular to the ground, is 1.9m. the length of the pole's shadow is 1.52m. what is the height of the building?

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
