You answer for 24x3+18x2-6x would be 102x
Answer:
Add 5 to remove the negative 5 from the left side.
Step-by-step explanation:
3x-5=19
3x-5(+5)=19
Answer:

Step-by-step explanation:
So we know that:

And that the two angles are vertical angles.
Since they are vertical angles, their measurements are equivalent. Thus, to find x, set the equations equal to each other:

Now, solve for x. Add 30 to both sides. The left side cancels:

Now, subtract 2x from both sides. The right cancels:

Thus, the value of x is 21.
The square root of 325 is 18.03
Answer:
(9-10x)(9+10x) (I think this is the answer but I'm not one hundred percent sure)
Step-by-step explanation:
First, you can recognize that both numbers (-100x^2 and 81) are a difference of squares, in which means that they both can be square routed. Then, plug in the square routes of the numbers into (9-10x)(9+10x). 9 is the square route of 81 and 10 is the square route of 100. Make sure that when you put the numbers in the parenthesis that there is one negative and positive number since a negative multiplied by a positive makes a negative, hence making 100 negative. I hope that helped.
