Answer:

The answer would be 16b^2 - 14b + 3

Step-by-step explanation:

In order to find this, we simply need to group the terms by their variable values. We will start with the b^2 terms.

5b^2 + 24b^2 - 13b^2 = 16b^2

Now we can use all of the b terms.

-5b - 8b - b = -14b

And finally, we'll do all the constants.

4 - 1 = 3

Using all three of these together will give us the simplified form.

Write an absolute value inequality that

fiasKO [112]

Answer:

All real numbers greater than or equal to -1 and less than or equal to 2

Step-by-step explanation:

Let

A_1 ------> the area of rectangle

A_2 ----> the area of triangle

we know that

$\left|A_1-A_2\right|\le 6$

Find out the area of rectangle

$A_1=4(x+2)=(4x+8)\ units^2$

Find out the area of triangle

$A_2=(1/2)(4)(5)=10\ units^2$

substitute

$\left|(4x+8)-10\right|\le 6$

Simplify

$\left|4x-2\right|\le 6$

First case (positive value)

$+(4x-2) \leq 6$

$4x \leq 6+2$

$4x \leq 8$

$x \leq 2$

Second case (negative value)

$-(4x-2) \leq 6$

Multiply by -1 both sides

$(4x-2) \geq -6$

$(4x \geq -6+2$

$4x \geq -4$

$x \geq -1$

therefore

The solution for x is the interval -----> [-1,2]

All real numbers greater than or equal to -1 and less than or equal to 2
