URGENT MAX 100 POINTS WILL BE REWARDED IF THE FIRST ANSWER NOT RELEVANT THAN I WILL CHOSE THE BEST ANSWER THANK YOU HAVE A SPECTACULAR DAY!!! A yacht race follows a triangle course that has been mapped on to a Cartesian plane. The scale on the axes indicates distances in kilometres. The race begins and ends at the origin?
a. Calculate the length of each leg of the race?
b. Calculate the total racing distance?
c. If an observer’s boat is located at the midpoint of the second leg of the race, calculate the distance between this boat and the finishing point?

Let the points be A,B,C

A(0,0)

B(24,16)

C(8,20)

#A

(leg3)

(leg1)

(leg2)

#B

We have to find perimeter

#C

The length of leg3=17.4units

step-by-step explanation:

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
