(12)(7)(6x)=504x

(12 * 7 * 6)(x)=504x

(7)(12)(6) + x=504+x

12(7 + 6x)=84+72x

12 + 7 + 6x=19+x

wee see that

A*B=(A)(B)

I believe the expression equals to 12(7+6x). You multiply 12 by everything but you can't multiply the x to everything so Itd be 84+72x. answer being C.

A hexagonal pyramid that has a slant height of 39 cm and its hexagonal base has a radius of 10√3 cm.
VMariaS [17]

Answer: 225

Step-by-step explanation:

Volume of the pyramid is calculated as 1/3 bh, where b is base and h is height

Given height as 39cm and a base of 10√3cm = 10 x √3, where √3= 1.73; base = 10 x 1.73 = 17.3

Slot the values into the formula:

Volume = 1/3 × 17.3 x 39

= 1/3 × 674.7 = 674.7/3

Volume = 224.9 approximately 225.

I hope this helps.

If f(x)=×^2+7x-5 and you divide by x-2, What is the quotient and remainder?
katrin [286]

Answer:

The quotient is : x+9

The remainder is : 13

Step-by-step explanation:

The question requires you to perform the long division method;

This will be;

x-2\sqrt{x^2+7x-5}

start with the x term in x-2 and the first term in the function, x², to get x then multiply the x with x-2 to get x²-2x and perform the operation below;

x-2√x²+7x-5 -----------to first get x and then multiply x*[x-2]⇒x²-2x

    -  x²-2x+0 ------------perform subtraction of like terms

---------------------

            9x-5  ----now divide this answer by x-2 ,starting with x and 9x

----------------------This will give , 9 then multiply  9 by x-2 to get 9x-18 and perform the subtraction operation as;

             9x-5

      -      9x-18

------------------------

                     13

So the answer will be; x+9 remainder 13

Which is 2/3 of 18 <br>A. 27<br>B. 8<br>C. 12<br>D. 6
ahrayia [7]

Answer:

C. 12

Step-by-step explanation:

We know you have the number 18 and the fraction 2/3. The problem is we want to find out what 2/3 of 18 is. Well, if 18 divided by the denominator of that fraction (3) is 6 than we just add 6 because the question is asking for 2/3 NOT 1/3.
