I'm pretty sure that the answer is 12C4 = (12p4)/4! = (12*11*10*9)/4*3*2*1 = 495

Hope this helps

2(1 − x) = 9(1 + 2x) + 52(1 − x) = 9(1 + 2x) + 5

marusya05 [52]

Solving the equation $2(1-x) = 9(1 + 2x) + 5$ we get $x=-\frac{3}{5}$

Step-by-step explanation:

We need to solve the equation $2(1-x) = 9(1 + 2x) + 5$ and find value of x

Solving:

$2(1-x) = 9(1 + 2x) + 5\\2-2x=9+18x+5\\Adding\,\,-18x\,\,on\,\,both\,\,sides:\\2-2x-18x=9+5\\Adding\,\,-2\,\,on\,\,both\,\,sides\\-20x=14-2\\-20x=12\\x=\frac{12}{-20}\\x=-\frac{3}{5}$

So, solving the equation $2(1-x) = 9(1 + 2x) + 5$ we get $x=-\frac{3}{5}$

What is the area of the base of a triangular prism if the volume is 210 ft3 and the height is 14 ft?

Oksi-84 [34.3K]

We have the area of the base of a triangular prism= a*b
the volume of triangular prism =a*b*c( where c is the height) so that 210=a*b*14 ==> 210= base area*14==> base area= 210/14

4/3 is the ratio between fruit punch and orange juice. For every 3 cups of orange juice she makes, she can make 4 fruit punches. An example:
If you replace x (orange juice) with 2, that'd mean there'd be 6 cups of orange juice because you'd multiply 3 and 2. Same goes to 4. 4 multiplied by 2 is 8, which means if she makes 6 cups of orange juice, she can make 8 cups of fruit punch.

Solve the equation.

elena55 [62]

Answer:

C: $x=-3$ or $x=4$

Step-by-step explanation:

To solve the equation $x^2-x-12=0$ we need to factor it

We are looking for two numbers that when multiplied give -12 and when added give -x

This means that when factored, the equation would be $(x-4)(x+3)=0$

Now we can set each of these equal to 0, which means that at

$x=-3$ and $x=4$ , the equation will equal 0
