Answer:
P = 10x + 4
Step-by-step explanation:
Formula to find perimeter:
P = 2(l + w)
P = 2(2x + 3x + 2)
P = 2(5x + 2)
P = 10x + 4
Answer:
The answer is -22x² - 14x.
Step-by-step explanation:
You have to eliminate the brackets by multiplying :



Next you can simplify but there is no common terms in this expression so it remains the same.
Median is the number in the middle when all the numbers are put in order.
Let's do that first.
30 52 61 65 68 68 69 75 78 85
Now if there's 10 numbers, 2 numbers are in the middle.
By counting in 4 on both sides, we know the two numbers are both 68, so 68 is the median.
A^2 + b^2 = c^2
8^2 + b^2 = 12^2
64 + b^2 = 144
b^2 = 144 - 64
b^2 = 80
b = sqrt 80
b = 8.9 ft <===
Answer: 30
Step-by-step explanation: Formula for Area of a triangle = 1/2 Base * Height. 12*5 = 60; 60/2 = 30.
