Is my answer correct??
Ivanshal [37]

Answer: Last option.

Step-by-step explanation:

For this exercise it is important to remember that a Right triangle is a triangle that has an angle that measures 90 degrees.

By definition, given a Right triangle, if you draw an altitutde from the vertex of the angle that measures 90 degrees (The right angle) to the hypotenuse, the measure of that altitude is the geometric mean between the measures of the two segments of the hypotenuse.

In this case, you have the Right triangle EFH  given in the picture attached.

You can notice that FG goes from the vertex of right angle (\angle F=90\° ) to the hypotenuse EH. Therefore, it divides the hypotenuse into two segments. These are:

EG and GH

Therefore, FG is the geometric mean of the segments EG and GH.

Answer:

<h2>the first ordered pair is (-2, -2)</h2><h2>the second ordered pair is (4,0)</h2>

Step-by-step explanation:

to find the missing values, plug in the given values into the equation:

x-3y=4

the first ordered pair:

we are given a y-value (-2), so lets plug it into the equation:

x-3*(-2)=4

now solve for the missing value:

x+6=4

x=4-6

x=-2

now plug in both x and y and check if the equation is true:

(-2)-3*(-2)=4

-2+6=4

6-2=4

4=4

the first ordered pair is (-2, -2)

the second ordered pair:

we are given a x-value (4), so lets plug it into the equation:

(4)-3y=4

now solve for the missing value:

-3y=4-4

-3y=0

y=0/-3

y=0

now plug in both x and y and check if the equation is true:

(4)-3*(0)=4

4-0=4

4=4

the second ordered pair is (4,0)

100 POINTS AND BRAINLIEST: The short sides of a rectangle are 2 inches. The long sides of the same rectangle are three less than
Wittaler [7]

Answer:

x= "a certain number of inches"

side a= x-3

side b= 2 inches

multiply:

Area= a(b)

A= (x-3)2

A= 2(x-3)

distribute:

A= 2(x-3)

A= (2*x) + (2*-3)

A= 2x-6

Area= 2(x-3)

Area= 2x-6

Step-by-step explanation:

The area of the rectangle is equal to the multiple of its two sides this is equal to two inches times an expression three less than a certain number "x". Using the distributive property, we can solve this expression further to find that the area of this rectangle is also equal to six less than doubling a certain number x.
