Perimeter formula
p = 2l + 2w
I reverse left-right side
2l + 2w = p
Move 2l to the right
2l + 2w = p
2w = p - 2l
Move 2 to the right
2w = p - 2l
w = (p - 2l)/2
Summary
p = 2l + 2w
2l + 2w = p
2w = p - 2l
w = (p-2l)/2
Answer:
c
Step-by-step explanation:
Answer:
A) Leg
Step-by-step explanation:
In a right triangle, the side that is opposite of the right angle is the hypotenuse. It is also the longest side of the triangle.
Since side 'a' makes up a right angle and it's a shorter piece, it is a leg of the triangle.
Hope this helps.
(8 + [7+1] 2 ÷ 4 × 1) ÷ 2^4
Let's focus on what's in parentheses first.
8 + 8 × 2 ÷ 4 × 1
8 + 16 ÷ 4 × 1
8 + 4 × 1
8 + 4
12
Now, to what is outside the parentheses:
Because of the way it is written, you will do 12 ÷ 2 first.
12 ÷ 2^4
6^4
