Log(18) - log(p+2)
because base of both logarithms is 10 that means we can merge them into one logarithm

the rule is as fallows:
log(b) - log(c) = log (b/c)
log(b) + log(c) = log(b*c)

since sign between our 2 logarithms is - that means that we need to divide

answer is:
log(18/(p+2))

Answer:In Heather's solution to the problem, she wrote and solved an equation.

Her work is:

Step 1: 1.08(x +9.01 +0.98 +5.01) = 21.87

Solving like terms

1.08(x+15}=21.87

dividing both side by 1.08

we get

x+15=21.87/1.08

x+15=20.25

subtracting both side by 13.9198

x=20.25-15

x=5.25

A shipping company offers various sized shipping boxes to its customers. Some of these boxes are cube-shaped, with equal height,

Vladimir79 [104]

A cube shaped box of side length equal to m foot has volume
$m*m*m= m^{3}$ foot cubed.

a.
Let v1 be the volume of the box with side length 1 ft.
and v2 be the volume of the box with side length x ft.

$V1=1^{3}=1$ (foot cubed)
$V2=x^{3}$ (foot cubed)

Vtotal= $V1+V2=1+x^{3}$ feet cubed

b.

by the "sum of cubes" identity:

$x^{3}+1=(x+1)( x^{2} -x+1)$ ,

this identity can be derived by dividing $x^{3}+1$ by (x+1), by long division.

c. Vtotal when x=3 feet is:

Vtotal= $V1+V2=1+3^{3}=1+27=28$ (feet cubed)
