Answer:the correct answer is c
Step-by-step explanation:
Answer:
a² + 4ab + 4b²
Step-by-step explanation:
Given
(a + 2b)²
= (a + 2b)(a + 2b)
Each term in the second factor is multiplied by each term in the first factor, that is
a(a + 2b) + 2b(a + 2b) ← distribute both parenthesis
= a² + 2ab + 2ab + 4b² ← collect like terms
= a² + 4ab + 4b²
Answer:
Step-by-step explanation:
The generic formula for the n-th term of an arithmetic sequence is ...
an = a1 +d(n -1)
where an is the n-th term and a1 is the first term.

Here, you have a1 = -12 and d = 4. Putting these numbers into the formula gives you what you are asking for:
an = -12 +4(n -1)
Answer:
J
Step-by-step explanation:
Step 1: solve for y
Step 2: graph y, use dashed line
Step 3: Shade in solutions, here y>3 so everything bigger then 3 is a solution.
D = rt
/t /t
D/t = r
80/16 = r
5 = r
Therefore r = 5ft/second
