I was only able to come up with the answer of 1. Here is my work (don’t mind the messy handwriting I was writing with my finger on my phone)
Answer:
6 by 3
Step-by-step explanation:
a rectangle as 2 equal sides. so if we know that it is 6 by 3, then 6+6+3+3
=12+6=18
the area of a rectangle is base * height. so 6 * 3 = 18
3a.
Explanation:
the mean, first of all, is the average. so, you need to find the average between 2 ans 4 since it has the same label. 2+4=6. 6/2=3
Answer: 3a
The ÷ sign is a pretty archaic sign for division. Most people will be using "/".
Anways, what I learned is PEMDAS
Parentheses
Exponents
Multiplication and Division (left to right)
Addition and Subtraction (left to right)
<span>(2− 1) + 3^2 ÷ 3
</span><span>1 + 3^2 ÷ 3
</span><span>1 + 9 ÷ 3
</span>1 + 3

The answer is D.
Hi the answer is b=180-a-c
We have to subtract a from both sides
a+b+c+-a=180- a
b+c= 180 - a
Now subtract c from both sides
b+c-c = 180 - a - c
b=180 - a - c
