Can someone please help me?!!!!
My name is Ann [436]
Firstly let’s assume she is correct and use an equal sign:
1/2(12x + 24) = 3(2x + 4)

Now simplify both sides:
1/2 • 12x = 6x
1/2 • 24 = 12
6x + 12

3 • 2x = 6x
3 • 4 = 12
6x + 12

And:
6x + 12 = 6x + 12
Therefore they are equivalent, she is correct.

A student says that if the hypothesis is false, an argument cannot be valid. How do you respond ?
Anton [14]
If a student tells me that an argument that has a false hypothesis cannot be valid, I would reply that we need to look carefully at the meaning of validity in the context of logic.  In everyday speech, we tend to use “valid” to mean the same thing as “true” or “accurate.”  In logic, this is not the way the term is used.

A population of geese grow in such a way that each generation is simply 2.2 times the previous generation. There were 3 geese in
ArbitrLikvidat [17]
This would produce a geometric sequence of the form:

g=3(2.2)^(n-1)

The sum of which is:

g=3(1-2.2^n)/(1-2.2) cleaning up a bit...

g=-3.6(1-2.2^n)

g(15)=-3.6(1-2.2^15)

g(15)=492764.6, since the number of geese must be an integer...

g(15)=492764

The perimeter of a rectangle is 176 m. The length is 4 m less than three times the width. Find the dimensions of the rectangle.
lutik1710 [3]

Answer:

Length = 65 m

Width = 23 m

Step-by-step explanation:

Width = w

Length = 3w - 4

Perimeter of rectangle = 176 m

2*(length + width) = 176

2*( 3w - 4 + w ) = 176

2* ( 4w - 4) = 176

2*4w - 2*4 = 176

      8w - 8 = 176    { add 8 to both sides}

           8w = 176 +8

           8w = 184

        8w/8 = 184/8

              w = 23 m

Length = 3w - 4

            = 3*23 - 4

            = 69 - 4

Length = 65 m
