Mathematics

Otrada [13]2 years ago

Vol=area x Height

length= 3
breadth= X
Height = 2

area must = half of 42 because to get the volume of 42cm cubed, you had to times the area by 2 so

42 devided by 2 is 21 so to find the length you myst do 21 devided by 3 which is 7

so the missing length is 7cm

Describe how you can tell that a fraction is reapeating and not terminating
GREYUIT [131]
<span> First, reduce the fraction to lowest terms, e.g. 8/6 = 4/3.

Look at the denominator. Split it into its prime factors. If its prime factors only consist of 2's and 5's, then it will be terminating.

Examples:
16 = 2 x 2 x 2 x 2, so terminating
25 = 5 x 5, so terminating
2000 = 2 x 1000 = 2 x (2 x 5) x (2 x 5) x (2 x 5), so terminating
12 = 2 x 3, so repeating (has prime factor 3, which is not 2 or 5)
13 = 13, so repeating (has prime factor 13, which is not 2 or 5)  Hope this helps!!

Answer: <em>(-3; -11)</em>

Step-by-step explanation:

\left \bigg \{ {\big{y=7x+10} \atop\big {y=-4x-23}} \right.\\\\7x+10=-4x-23\\7x+10-10=-4x-23-10\\7x=-4x-33\\7x+4x=-4x-33+4x\\11x=-33\\11x \div 11=-33 \div 11\\x=-3\\\\y=7x+10\\y=7 \times (-3)+10=-21+10=-11

What is this problem -12=4(x-7)-8x
Fofino [41]

-12=4(x-7)-8x

One solution was found :

                  x = -4

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :


                    -12-(4*(x-7)-8*x)=0


Step by step solution :

Step  1  :

Equation at the end of step  1  :

 -12 -  (4 • (x - 7) -  8x)  = 0

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :


  4x + 16  =   4 • (x + 4)


Equation at the end of step  3  :

 4 • (x + 4)  = 0

Step  4  :

Equations which are never true :

4.1      Solve :    4   =  0

Hope this helps you, Have a nice day.
