Consider the quadratic equation 4x2 – 11x – 3 = 0. Which of the following shows this equation rewritten and ready to solve using factoring by grouping?

Step-by-step explanation:

we have

Solve the quadratic equation

we know that

The formula to solve a quadratic equation of the form

is equal to

in this problem we have

so

substitute in the formula

therefore

Rewrite the expression

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
