a) 4x +6
Add up all the sides to calculate perimeter
1. x midpoint: (-9+4)/(2) = -2
2. y midpoint: (3+7)/(2) = 5
3. The midpoint is (-2,5)
Pythagorean Theorem is
a ²+ b ² = c ²
a and b are the shorter sides, while c is the hypotenuse, or longest side. Let’s say the side we are looking for is “b”.
Let’s first rearrange the equation, then sub in.
a ²+ b ² = c ²
b ² = c ²- a ²
b = √ (c ²- a ²)
b = √(17 ²- 15 ²)
b = √(289-225)
b = √ 64
b = 8
Answer:
3/10
Step-by-step explanation:
Percent is basically the number over 100.
In this case, 30% is equal to 30/100, which can be simplified to 3/10.
Thus, the answer is 3/10 of the audience.
Hope this helps!
