CB = DA = √3*3+1*1 = √10
CD = BA = √2*2+1*1 = √5
Sum is 2√10 + 2√5 ≈ 10.8. So answer A.
Answer:
y=1/2x+6
Step-by-step explanation:
for the equation you start with finding the rate of change (wich is what y changes by as x 9minths) in creases by 1) and then add the Y-intercept, so it would be Y=1/2x+6
Formula:
Y=△y•x+b(y-int)
To find y intercept find what <em>y </em>is when x is 0, or in this case you know it comes out 6 feet tall, so that is what the Y int. is
The perimeter would just be the equation that they provided to you multiplied by 3 because a triangle has 3 sides, and it is an equilateral triangle, so every side is the same. You do the distributive property to solve the equation and get your final answer.
The answers are 6, 7, 8, and 11.
Hope this helps! :D
