Answer:

a = 16

Step-by-step explanation:

6 = a/4 + 2

4 = a/4 Subtract 2 from both sides

16 = a Multiply 4 to both sides

Answer: a=16

Step by Step Explanation

Step 1: Switch sides so that the product is last. It is now a/4=2=6

Step 2: Subtract 2 from both sides. 2-2=0 6-2=4

Step 3: Now we have a/4=4. Multiply both sides by 4.

Step 4: 4 times 4 equals 16.

a=16

To check ur answer, plug it into the equation. 16/4+2=6

Let's check if it's right.

16/4=4 4+2=6 6=6 This is correct

Can someone please help me <br> Factor completely <br><br> 9-6a-24a^2

-24a^2 - 6a + 9
You don't want a negative in front of the variable that is being squared.
-1(24a^2 + 6a - 9)
-3(8a^2 + 2a - 3)
now we use the A C method. what two numbers multiply to equal A×C (8×-3) and add to be B (2)?

6 and -4

-3(8a^2 + 6a - 4a - 3) factor by grouping
-3(2a(4a + 3) -1(4a + 3))
-3(2a - 1)(4a + 3)

Describe lengths of three segments that could not be used to form a triangle. Segments with lengths of 5 in., 5 in., and ______

Vesna [10]

Answer:

$c = 11$

Step-by-step explanation:

Given

Let the three sides be a, b and c

Such that:

$a = b= 5$

Required

Find c such that a, b and c do not form a triangle

To do this, we make use of the following triangle inequality theorem

$a + b > c$

$a + c > b$

$b + c > a$

To get a valid triangle, the above inequalities must be true.

To get an invalid triangle, at least one must not be true.

Substitute: $a = b= 5$

$5 + 5 > c$ $===>$ $10 > c$

$5 + c > 5$ $===>$ $c > 5 - 5$ $===>$ $c > 0$

$5 + c > 5$ $===>$ $c > 5 - 5$ $===>$ $c > 0$

The results of the inequality is: $10 > c$ and $c > 0$

Rewrite as: $c > 0$ and $c < 10$

$0 < c < 10$

This means that, the values of c that make a valid triangle are 1 to 9 (inclusive)

Any value outside this range, cannot form a triangle

So, we can say:

$c = 11$ , since no options are given

Ill give brainliest to the correct and best explained answer :))

mezya [45]

Answer:

Step-by-step explanation:

To find the median, arrange the data in ascending order

10,20,30,40,50,60,70,80,90

Number of data = 9 . It is a odd number

So, median will be the (n+1)/2 th term

$\left(\dfrac{9+1}{2} \right)^{th \ term} = (\dfrac{10}{2})^{th \ term} = 5^{th \ term}$

Median = 50
