For this question you need to find the Lowest Common Multiple (LCM) of 9 and 12. We do this by finding the prime factorization of each number.
9 = 3 x 3
12 = 3 x 4
The LCM is found by multiply the highest number of each factor.
LCM = 3 x 3 x 4 = 36.

What is the solution to the equation below? <br> Vx + 3 = x - 3 <br> A. 3<br> B. 6<br> C. 5<br> D. 4
kherson [118]

Answer:

6

Step 1: Solve Square Root

Vx+3=x-3

x+3=(x-3)^2 (squared both sides)

x+3=x^2-6x+9

x+3-(x^2-6x+9)=0

(-x+1)(x-6)=0 (factor left side of equation)

-x+1=0 or x-6=0

x=1 or x=6

When you plug it in to check

1 (Doesn't Work)

6 (Work)

Therefore, 6 is your solution.

Describe and correct the error in writing the phrase as an expression?
lesantik [10]

Answer:

12 < x

Step-by-step explanation:

In writing 12 less than a number x, the expression, 12 - x is wrong because "less than" is not the same thing as "minus" (-). Rather, the sign, "<" should have been used as follows:

12 < x.

ALGEBRA 1 HELP URGENT!!
butalik [34]
Here, Sequence : -2, -6, -18, -54
Common Ratio = a₂/a₁ = -6/-2 = 3
As the expression is in negative sign, it's sequence will be -3ˣ
Where x = number of terms in the sequence [ By this rule, you can calculate the unknown nth number]

In short, Option C is your answer!!!!

Let me know, if you have some doubt.

Answer:

#3   1/6, 1/6, 1/2, 1/3, 5/6.

#4   3/12, 4/12, 5/12, 8/12, 9/12

Step-by-step explanation:

#3 is numbers out of six (fractions).

#4 is the same thing.  You add all of the numbers (4, 3, and 5) to get the total and then you subtract to get the probability.

These are all I know.
