Answer:
The answer is B
Step-by-step explanation:
1. 2.50 x 2 is $5
2. 2.50 x 4 is $10
3. 2.50 x 3 is $7.50
4. 5 + 10 + 7.50 is 22.50 so you know the total should be 22.50.
5. It cant be A because 2.50 x 2 is 5 then timesing that by four would make 20 and then by 3 that would make $60 not $22.50
6. It is B because 2 + 4 + 3 is 9, 9x2.50 is 22.50
You need the starting point and the end point and count how long it took to get to one point to the either
Assuming it’s a equilateral triangle the answer is 8sqrt(3)
Height 12cm
Cut the triangle in half so it becomes a 30-60-90 triangle
So 12/sqrt(3)=x and the side you want is 2x so it is 24/sqrt(3) for each side but you need to make sure you simplify it to (24sqrt(3))/3 and then one more time to 8sqrt(3)
I Think You Should Add Them Together.
3×(n+1) = 5n
3*(n+1)-(5*n)=0
n = 3/2 = 1.500
