Answer:
<h2>

</h2>
Step-by-step explanation:

Therefore it's geometric sequence with common ratio of 6

The factored form would be (x+3)(x+4) since 4*3 = 12 and 4+3 = 7
value of x is
and value of y is 
Step-by-step explanation:
We need to find Which expression could be substituted for y in the second equation to find the value of x
The given equations are:

For putting value of y in second equation, we will find from equation 1
From equation 1:

Putting value of y i.e y=10+2x in equation (2) to find value of x

So, now finding value of y by putting value of x= -29/4 in eq(1)

So, value of x is
and value of y is

Answer:
1436.76 in.^3
Step-by-step explanation:
This question means to find the volume of a sphere with a diameter of 14 inches. The formula for the volume of a sphere is 4/3πr^3, so we need to find the radius, which is half the diameter. Half of the diameter is 7 inches, so now we can plug in our values to find the volume is about 1436.76 cubic inches.
