The answer would be -15x+36. To solve this equation, you would first use distributive property and distribute the -9 to the values inside the parentheses (or multiply them). So, you would multiply -9 and x and -9 and -4 to get -9x+36-6x. Then, you combine like terms, which are -9x and -6x to get -15x. You can't simplify any further without knowing the value of x. Hope this helps!
Answer:
199.5 ft^3
Step-by-step explanation:
to find your answer you simply multiply all the measurements together
19 * 1.5 * 7 is your equation
19 * 1.5 * 7 = 199.5
it is 199.5 ft^3
Answer:
360,360
Step-by-step explanation:
This is called a Permutation with repetition, we want to know in how many ways we can arrange a certain ammount of elements (normal permutation), BUT some of those elements are identical.
The formula we use in these cases is:

where n is the total amount of elements, n1 is the amount of repeated elements of the type 1, n2 is the amount of repeated elements of the type 2, ni is the amount of repeated elements of the type i.
In this particular case we have:
(total amount of shirts)
(small shirts)
(medium shirts)
(large)
(extra large)
then the amount of orders the shirts can be sold at (arranged) is:

Answer:
0.56
Step-by-step explanation:
Since 1/10 is 0.1 as a decimal you will then change it to 5.6 x 0.1 which would equal 0.56
