Answer:

67 units squared

Step-by-step explanation:

First, you multiply all the combinations possible with the 3 values.

5x1.5, 5x4, 1.5x4

But there are 2 of every side so you multiply each by 2.

5x1.5x2 = 15

5x4x2 = 40

1.5x4x2 = 12

12+40+15 = 67

Let a = 2i + 3, b= i – 1, and c= -3i + 2. Which expression is equivalent to a -b- c?A. –2i +4B. 4i + 2C. 4i + 4D. -2i + 2
34kurt

Given:

\begin{gathered} a=2i+3 \\ b=i-1 \\ c=-3i+2 \end{gathered}

You know that:

a-b-c=(2i+3)-(i-1)-(-3i+2)

In order to solve the operation, you can follow these steps:

1. Distribute the negative signs. Remember the Sign Rules for Multiplication:

\begin{gathered} +\cdot+=+ \\ -\cdot-=+ \\ +\cdot-=- \\ -\cdot+=- \end{gathered}

Then:

=2i+3-i+1+3i-2

2. Combine the like terms (add the Real Parts and add the Imaginary Parts):

=4i+2

Hence, the answer is: Option B.

Which is the rate of change for the interval between 2 and 6 on the x-axis?
nadezda [96]

Answer:

3

Step-by-step explanation:

I think you misses attaching the photo, so please have a look at my photo for your better understanding.

We know the formula for rate of change of the  parabola line:

\frac{f(b)- f(a)}{b-a}

Given here:

a= 2 => f(a) = 2

b=6 => f(b) = 2

Substitute all the values into the function, we have:

\frac{14-2}{6-2} = 3

So the rate of change is 3
