One way: log(A)-log(B) = log(A/B) right?

So, log( x^2-9/(x+3))

Now x^2-9 = (x+3)*(x-3), and x^2-9/(x+3) = x-3,

so log(x^2-9)-log(x+3) = log(x-3),

Indeed for all x but for x = -3, but probably no one asks you about that detail?

Find the missing angle
Natasha_Volkova [10]

Answer:

56deg

Step-by-step explanation:

A triangle has 180deg.

180 = 68 + 56 + x       >> add 68 and 56

180 = 124 + x              >> subtract 124 from both sides

56 = x

The missing side is 56deg

About 3.9 * 10 ^ 7 people live in California. About 1.3 * 10 ^ 6 people live in Maine. About how many more people live in Califo
TiliK225 [7]

Answer:

3.7*10⁷ people.

Step-by-step explanation:

Estimated population of California = 3.9*10⁷ people

Estimated population of Maine = 1.3*10⁶ people.

Let x represent the estimated number of people that live in California more than Maine.

The number of people that live in California more than Maine can be found by finding the difference between the population of California to Maine.

No. Of people living in California - no. Of people living in Maine = estimated no of people that live in California more than Maine.

X = 3.9*10⁷ - 1.3*10⁶

X = 3.7*10⁷ people

About 3.7*10⁷ people live more in California than Maine
