Answer:

x = -3

Step-by-step explanation:

Start by distributing the 4 to the terms in the parentheses:

4(-4x)+4(-1)+x+3=44

-16x-4+x+3=44

Combine like terms

-15x-1=44

Add 1 to both sides

-15x-1+1=44+1

-15x=45

Divide both sides by -15

x = -3

Analyze the diagram below and complete the instructions that follow.

Umnica [9.8K]

Answer:

$x= 7, y=4\sqrt{2}$

Correct option B.

Step-by-step explanation:

The diagram shows a trapezoid with a base angle of 45° and the other base angle of 90°.

We have completed the diagram to draw a perpendicular line over the base of height h=4. A triangle is formed with an angle of 45°.

Recall a right triangle with angles of 45° is isosceles, thus the base and the height are h=4. Please check the diagram below.

For that triangle, we apply Pythagora's Theorem:

$y^2=4^2+4^2=2*4^2$

Thus:

$y=\sqrt{2*4^4}=4\sqrt{2}$

$y=4\sqrt{2}$

The base of the trapezoid x is h + 3 = 7

Thus:

$\mathbf{x= 7, y=4\sqrt{2}}$

Correct option B.

Show me the equation for 3 less than 5 times a number is 12 use X for the variable

ANEK [815]

Answer:

The required equation is 5x - 3 = 12

Step-by-step explanation:

We have to find the equation for the given condition

Let the number be x as given in the equation

Now according to the condition

5 time the Number is 5 *x = 5x

Three less then 5 time the Number would be 5x - 3

And all of it is equal to 12

Which gives us the equation

5x - 3 =12

The required equation is 5x - 3 = 12

Xyz-qrs and the scale factor from xyz to qrs is 2/5. what is the length of side rs?

raketka [301]

Answer:

RS = 10

Step-by-step explanation:

We are told that to get ∆QRS, the scale factor of ⅖ was used. To get side RS, we would multiply the side length of the side that corresponds to RS.

YZ corresponds to RS.

YZ = 25

Thus,

RS = 25*⅖

RS = 10
