Answer:

The number 3 makes this statement true.

x=3

Step-by-step explanation:

Given the equation:

(12*3)*6=12*(x*6)

Using the order of operations, we can evaluate the terms in the parentheses through the process of multiplication:

36*6=12*6x

Multiply the terms on both sides of the equation:

216=72x

Finally, divide both sides of the equation by the coefficient of x, which is 72:

3=x

x=3

-

Let's check our work by substituting the solved x value for

(12*3)*6=12*(3*6)

36*6=12*18

216=216

Since both sides of the equation are equal to each other, our solution is correct!

Answer:

3

Step-by-step explanation:

12 times 3 = 36

36 times 6 = 216

12(x times 6)

(12)6x

72x

216 = 72x

216/72 = 3

What value, entered in the blank below, would make the two expressions equivalent? Expres
malfutka [58]

Answer:

The value is -3

Step-by-step explanation:

Here in this question, we are interested in making the expressions on both sides of the equation equal. But we seek a particular value or number which when placed in front of the quadratic expression on the right hand side makes the equations equal.

To get this done with, we will need to factorize the expression on the left hand side of the equation.

Thus, we can write;

-27x^2 + 9x + 12 as 3(-9x^2 + 3x + 4)

What do we notice? we can see that the now factored quadratic expression resembles what we have on the right hand side asides there fact that we are not there yet in terms of sign.

Thus, we can finally write ;

-27x^2 + 9x + 12 as -3(9x^2 -3x -4)

This exactly gives the expression on the right hand side

Thus the value to place in the blank is -3

Using synthetic division, find (x^4 − 2) ÷ (x + 1).
damaskus [11]
-1 is the rest, because its degree is smaller than that of the divisor and therefore can not continue dividing.
 x ^ 3 - x ^ 2 + x -1 is the quotient.

In the first week of July a record 1120 people went to the local swimming pool in the second week 105 fewer people went to the p
Westkost [7]

Answer:

25%

Step-by-step explanation:

The number of people who went to the local swimming pool in the;

first week = 1120

second week ( 105 fewer people) = 1120 - 105 = 1015

third week (135 more people) = 1015 + 135 = 1150

fourth week (310 fewer people|) = 1150 - 310 = 840

The percent decrease in the number of people who went to the pool over these four weeks

= (1120 - 840)/1120 * 100%

= 280/1120 * 100%

= 1/4 * 100%

= 25%

It means that the number of people who went to the local swimming pool over the 4 weeks decreased by 25%
