We are given the equation

$-3|x|+2x-1$

We are told that x=-5, so let's substitute that value into the equation:

$=-3|-5|+2x-1$

The absolute value sign $|x|$ means that any positive number will remain positive and any negative number will be changed to positive in these brackets

$-3(5)+2(-5)-1$

Now, simplify

$=-15-10-1$

And simplify again

$\boxed{=-26}$

This is your answer. Let me know if you need any clarifications, thanks!

Complete the parts in each step to find the area of each trapezoid?

Sergio039 [100]

The area of the trapezoid is 20 in².

Solution:

Given data:

Length of the bottom base = 7 in

Length of the top base = 3 in

Height of the trapezoid = 4 in

Step 1: Area of the trapezoid formula,

$$A=\frac{b_{1}+b_{2}}{2} \times h$

Step 2: Substitute the given values in the formula.

$$A=\frac{7+3}{2} \times 4$

Step 3: Add 7 and 3.

$$A=\frac{10}{2} \times 4$

Step 4: Divide 10 by 2, we get

$A=5 \times 4$

Step 5: Multiply 5 by 4, we get

A = 20 in²

The area given in the picture is wrong.

The area of the trapezoid is 20 in².

Need help please and thank you

It would be C because it’s asking you to multiple 3/4 by 3/4 sense there is a 2 exponent. And in order to multiply fractions you multiply across the top and bottom and then simplify. Sense c is already simplified that would be your answer. 3 x 3
4x4 9/16 or c
