Answer:
3(3x^2 + 5)
Step-by-step explanation:
step 1: find out the greatest common factor (GCF) of the number 9 and 15
ex: 9x^2 + 15x (3 * 3x^2 + 3 * 5)
step 2: factor out the common term 3
ex: 3 * 3x^2 + 3 * 5 (3 * 3x^2 + 5)
step 3: simplify the equation
3 * 3x^2 + 5 [3(3x^2 + 5)]
$26.60, take 72/50.40 to find how much money it is per minute. Set that equal to 38/x- x being the unit price you’re trying to find. Then cross multiply to get $26.60

Answer:
- 8
Step-by-step explanation:
An equation in the form y = mx + c ( m is the slope and c is the y- intercept )
Has a constant rate of change = m
given
= 12 + (n - 1)(- 8) ← distribute and simplify
y = 12 - 8n + 8
y = - 8n + 20 ← in the form y = mx + c
with constant rate of change = - 8
Answer:
The mammoth died 17.190 years ago.
Step-by-step explanation:
Given information:
- Half-life of C-14 is 5.700 years.
- Living elephant bones commonly contain about 40% C-14.
For every 5700 years, the elephant's bones losses a half-life of C-14. And supposing that the living mammoth bones had the same percentage of C-14.
If the mammoth when living has 40%, then:
- After 5.730 years, the mammoth bones will contain 20%.
- After 11.460 years(2 half-lives), the mammoth bones will contain 10%.
- After 17.190 years(3 half-lives), the mammoth bones will contain 5%.
