Each number is the number before it multiplied by 1.1
And since it is multiplied, there is a common ratio and so it is a geometric sequence.
3 x 1.1 = 3.3
3.3 x 1.1 = 3.63
And it goes on.
Hope this helps :)
Answer:
A. 6 hours
B. No students studied for 6 hours
C. 4 students
(I’m just using a educated guess for B)
Answer:
3(a - b)(a + b)
Step-by-step explanation:
Factorize: (2a - b)² - (a - 2b)²
- Different of Perfect a Square rule: a² - b² = (a + b)(a - b)
(2a - b)² - (a - 2b)² = [(2a - b) + (a - 2b)] × [(2a - b) - (a - 2b)]
1. Distribute and Simplify:
Distribute the (+) sign on the first bracket and simplify: [(2a - b) + (a - 2b)] → 2a - b + a - 2b → (3a - 3b)
Distribute the (-) sign on the first bracket and simplify: [(2a - b) - (a - 2b)] → 2a - b – a + 2b → (a + b)
We now have:
(3a - 3b)(a + b)
2. Factor out the Greatest Common Factor (3) from 3a - 3b:
(3a - 3b) → 3(a - b)
3. Add "(a + b)" back into your factored expression:
3(a - b)(a + b)
Hope this helps!
Answer:
Step 2
Step-by-step explanation:
Michelle's step in trying to solve the equation is given below:

Michelle made a mistake in Step 2.
The right hand side of Step 1: 
Rather, the correct sum is:

Answer:
A = 1.125
Step-by-step explanation:
A = lw
l =1.5
and w =.75
A= 1.5* (.75)
A = 1.125
