Answer:

x = 0 or x = -2

Step-by-step explanation:

x^4+8x=0

Step 1: Factor left side of equation.

x(x+2)(x2−2x+4)=0

Step 2: Set factors equal to 0.

x=0 or x+2=0 or x2−2x+4=0

x=0 or x=−2

In your own words, write a verbal expression for the following algebraic expression.<br> 18p

maxonik [38]

Step-by-step explanation:

18p is a multiplication expression in itself.

It could be written as 18 x p. I am confused on what you mean as 'verbal' so i'm gonna take a wild guess and say word form.

The initial population of a town in the year 2010 was 20 000. By 2014, the population had grown exponentially to 32 500 people.

stiv31 [10]

Answer:

P = 20000×1.625^(n/4)

Step-by-step explanation:

An exponential equation can be written using the given data:

value = (initial value)×(growth factor in period)^(n/(period))

Here, the growth is by a factor of 32500/20000 = 1.625, and the period is 4 years. Then your exponential equation is ...

P = 20000×1.625^(n/4)
