Problem 1) Line n is the line of symmetry (not line o) because we can fold the lower half to match up with the upper half. The folding line is over line n.
Problem 2) I agree. Nice work on getting the correct answer. The folding line is a vertical line through the center
Problem 3) It's hard to say for sure, but I think the top left corner is NOT reflective over any line of symmetry no matter how you rotate it. So I would uncheck that box. I agree with your other choices though. Great job with those.
The matching of definitions and terms are done below.
- Some number increased by two ⇒ b + 2
- A variable decreased by two ⇒ x – 2
- Product of an unknown value and two ⇒ 2z
- Quotient of some number and two ⇒ a ÷ 2
- An unknown value squared ⇒ y²
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Match the verbal expression (term) with its algebraic expression (definition).
Some number increased by two ⇒ b + 2
A variable decreased by two ⇒ x – 2
Product of an unknown value and two ⇒ 2z
Quotient of some number and two ⇒ a ÷ 2
An unknown value squared ⇒ y²

Answer:
Step-by-step explanation:
3a+10-4q+7a-4q-6 combine terms
10a-8q+4
The anwser is 17 and 3. 17+3=20, and the difference is 14!
