To find the area of a rectangle the formula is:

Area = length * height

A = L * H

In this case:

L = 3x

H = 2x

^^^In-put these values into the equation given above

A = 3x * 2x

Now you must multiply them together.

When multiplying numbers with variable(s) you multiply the number portion normally ( 3 * 2 = 6).

Multiplying variables is slightly different. The matching variables (x and x) will become one "x" and have an exponent attached to the x.

What will the exponent be? If a variable has no visible exponent it can be assumed that it has an exponent of 1. When multiplying variables the exponents on each variable will be <em>sumed </em>together and attached to the final variable:

x^{1} *x^{1} = x^{1+1} = x²

Now combine the product of the numbers with the product of the variables:

Area = 6x²

Hope this helped!

What numbers are zeros of g(x) = x^2 - 2x - 4? take your time if you need to!
ipn [44]

Answer:

x = 1 + \sqrt5, x = 1 - \sqrt5

Step-by-step explanation:

Hello!

We can solve the quadratic by using the quadratic formula.

Standard form of a quadratic: ax^2 + bx + c = 0

Quadratic Formula: x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}

Given our Equation: g(x) = x^2 - 2x - 4

  • a = 1
  • b = -2
  • c = -4

Plug the values into the equation and solve.

<h3>Solve</h3>
  • x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}
  • x = \frac{-(-2)\pm\sqrt{(-2)^2 - 4(1)(-4)}}{2(1)}
  • x = \frac{2\pm\sqrt{4 +16}}{2}
  • x = \frac{2\pm\sqrt{20}}{2}
  • x = \frac{2\pm\sqrt{4 * 5}}{2}
  • x = \frac{2\pm(\sqrt4 * \sqrt5)}{2}
  • x = \frac{2\pm2\sqrt5}{2}
  • x = 1 + \sqrt5, x = 1 - \sqrt5

The distribution of the diameters of a particular variety of oranges is approximately normal with a standard deviation of 0.3 in
In-s [12.5K]

Answer:

The correct answer is C.

Step-by-step explanation:

67^{th} percentile is represented as the value of probability in the norma distribution.

We look for a z-value with a left-tail of 0.67.

z=0.44

where,

z=\frac{x-M}{SD}

M: mean

SD: standar deviation

x=z×SD+M=0.44×0.3+M=M+0.132

The diameter of an orange at the 67^th percentile is 0.132 inch above the mean.
