What is the GCF of 12x and 44xy

Answers

Answer 1
Answer: 12x=4x\cdot3\n\n44xy=4x\cdot11y\n\nGCF(12x;\ 44xy)=4x
Answer 2
Answer: If we don't know what 'x' and 'y' are, the best we can say is that the GCF is 4x .
But 'x' and 'y' can easily take on values that would change the GCF.

Which set of numbers can represent the lengths of the sides of a right triangle? Round to the nearest whole number. 4, 4, 4 4, 6.93, 8 11.2, 16.2, 19.2

Answers

Answer with explanation:

A set of numbers that is triplet is said to form the sides of a right triangle, if it satisfies Pythagorean Theorem,which states that

Square of longest side is equal to sum of Squares of other two sides.

1.First triplet=4,4,4

As, 4²≠4²+4²

Hence it does not form Pythagorean triplet.

2. Second triplet=4, 6.93, 8

Largest side length =8

8²=64

Sum of squares of two smaller sides =(6.93)²+4²

 =48.0249+16

=64.0249

=64

3. Third triplet=11.2, 16.2, 19.2

Largest side length =19.2

(19.2)²=368.64

Sum of squares of two smaller sides =(11.2)²+(16.2)²

 =125.44+262.44

 =387.88

=388(approx)

Option B ⇒4,6.93, 8

Hello,

A: 4 , 4 , 4 not right triangle

B: 4 , 6.93 , 8  or 4²+6.93²=64,0249 ≈64=8²

C: 11.2 , 16.2 , 19.2 or 11.2²+16.2²=387,88 =(19,69...)²

The best choice is B



All are equivalent except x<-2, x-2<4, 2x<-4, x-2<-4 ?

Answers

To figure out which is not equivalent to the others,, we must solve each option provided. x < -2 is already solved,, so there is no need to do any work that option.
The first step for solving x - 2 < 4 is to move the constant to the right side and then change its sign.
x < 4 + 2
Now add the numbers together to get your final answer.
x < 6
This means that we have one option that equals x < -2 and one option that equals x < 6.
Let's now solve 2x < -4 to see what that one equals. In order to solve this,, we need to divide both sides of the inequality by 2.
x < -2
Now we can see that it looks like all of the expressions are equivalent except for x - 2 < 4. Before we can confirm this though,, let's solve for x - 2 < -4. The first step for solving this is to move the constant to the right side and change its sign.
x < -4 + 2
Now calculate the sum of these two numbers to get your final answer.
x < -2
This tells us that all of the options are equivalent except for x - 2 < 4,, or option B.
Let me know if you have any further questions.
