Figure ABCD has vertices A(−3, 2), B(2, 2), C(2, −4), and D(−3, −2). What is the area of figure ABCD?

Answers

Answer:

The area of the figure ABCD is $25\ units^(2)$

Step-by-step explanation:

we have

$A(-3, 2), B(2, 2), C(2, -4), D(-3, -2)$

using a graphing tool

Plot the figure

see the attached figure

The figure is a trapezoid

The area of the trapezoid is equal to

$A=(1)/(2)(AD+BC)AB$

Find the distance between the points in the graph

we have

$AD=4\ units$

$BC=6\ units$

$AB=5\ units$

substitute

$A=(1)/(2)(4+6)5=25\ units^(2)$

Answer:

I believe 25 square units is the right answer.

What is 5d - 10 = 20

Answers

Here is your equation:

$5d-10=20$

In this equation, you're looking for the value of d alone. That means you would have to move everything next to the variable to the other side. You can do that by doing the opposite of what's being done to it.

In this equation, 5d is being subtracted by 10(-10). The opposite of that is adding 10(+10). You would have to add 10 to both sides, since -10 and +10 cancel out each other.

The first thing you are going to do is add 10 to both sides.

$5d-10+10=20+10 \n 5d = 30$

Now you're left with the equation 5d=30. Remember that you're looking for d alone. In the current equation, d is being multiplied by 5(5d ⇒ 5 × d). Again, you're going to do the opposite of what's being done to it. The opposite of multiplying is dividing, therefore, you're going to divide both sides by 5, since the 5 divided by 5 is 1, which cancels out the 5.

Divide both sides by 5.

$(5d)/(5) =(30)/(5) \n \nd=6$

That means the answer to your equation is d = 6.

Answer:

d = 6

Step-by-step explanation:

Let us follow these steps to make d the subject.

First, add 10 to both sides.

5d - 10 = 20

5d = 10+ 20

5d = 30

Divide both sides by 5.

d = 6

80 POINTSSolve for x. Use the completeing the square method. x^2+8x=7

Answers

Answer:

x = -4 ±√23.

Step-by-step explanation:

x^2 + 8x = 7

(x + 4)^2 - 16 = 7

(x + 4)^2 = 23

x + 4 = ±√23

x = -4 ±√23.

Answer: The correct answer is C.

Step-by-step explanation:

⇒ $x^(2) +8x+16$

⇒ which is also, $(X+4x^(2) ) = 23$

⇒ So, $x + 4$ is a square root of 23.

⇒ Then, it could be positive or negative one:

So that's why the answer would be C.
