That would be the same as : 10 × (x + 8)
Okay, so it's asking for the product of 10, and the sum of 8 and k. Sum is the answer to an addition problem, so that would make the last of it 8 + k. And we'd be multiplying this with 10, so that would make it : 10 × (x + 8)
The factors of 25 and 60 would be 5. 25 divided by 5 is 5 and 60 divided by 5 is 12.
So here is what the distributive property looks like.
a(b+c)=a*b+a*c but we are going to rewrite a*b and a*c as 5*5 and 12* 5
a(b+c)=5*5+12*5
So i'd say its 5*5+5*12 i hope this helps
TanA = 6/8
or 3/4 when simplified
Answer:
<em>11 years</em>
Step-by-step explanation:
This is a case of exponential decay.
Let n = number of years; p = population after n years; a = initial population; r = rate of decay
p = a(1 - r)^n
Now we substitute the numbers we know leaving n as the only unknown.
100 = 250(1 - 0.08)^n
100 = 250(0.92)^n
Divide both sides by 250.
0.4 = 0.92^n
Take the log base ten of each side.
log 0.4 = log 0.92^n
Use log rule: log a^n = n * log a
log 0.4 = n * log 0.92
Divide both sides by log 0.92

n = 10.989
