We are given expression: 3a^3x(4a^2bcx^3)

3a^3x is in front of Parenthesis.

So, we need to apply multiplication operation there.

We need to multiply like terms( numbers by number and variables by variables).

First we multiply 3 * 4, it gives 12.

Now, a^3 * a^2. In order to multiply a^3 * a^2, we need to apply product rule of exponents.

According to product rule of exponents, when bases are same, we just need to add the exponents by keeping same base.

Therefore, a^3*a^2=a^{3+2}=x^5

On the same way, we can apply apply product rule of exponents on multiplication of

x and x^3.

x * x^3 = x^{1+3} = x^4.

Therefore, final answer would be

3a^3x(4a^2bcx^3)=12a^5bx^4.

Answer:

When you multiply you add exponents on like terms and multiply coefficients. The 3 is the coefficient of a^3x and 4 is the coefficient of a^2bcx^3. The a's are like terms and x's are like terms. There is only one use of b and c. So, multiplying coefficients -- 3*4 =12. Multiplying a^3 times a^2 equals a^5, and x times x^3 equals x^4. Answer is 12a^5bcx^4.

How many numbers between 111 and 100100100 (inclusive) are divisible by 333 and 101010?
EleoNora [17]
If the numbers that we are checking divisibility for are between 1-100, there are 3 numbers.

30, 60, and 90 are all divisible by both 3 and 10 because both 3 and 10 are factors of these 3 numbers.

There are 52 colas and 26 lemon-lime sodas in the cooler. What is the ratio of colas to lemon-lime sodas?
sergejj [24]
Hi there.

If there are 26 lemon-lime sodas and 52 colas, then that means our ratio is going to be 52:26; however, this is not simplified as both of these are even numbers. To simplify, divide both of these numbers by 26.

26 / 26 = 1
52 / 26 = 2

Our new and simplified ratio of colas to lemon-lime sodas is going to be
2:1.

I hope this helps!

a rectangle is transformed according to the rule r0, 90º. the image of the rectangle has vertices located at r'(–4, 4), s'(–4, 1
AleksandrR [38]
Graph images undergo transformations, one of the types of transformations are rotations.
rotation is done when each point of the image rotates 90° around a point in the counterclockwise manner. 
when rotation is done, (x,y) -> (-y,x)
therefore when taking points from image to original then the reverse is done ;
(-y,x) --> (x,y)
the coordinates of  image point q' is (-3,4)
before rotation then the coordinates are (4,3)
answer is (4,3)
