You are multiplying the 3x by 6 which means c is correct
Answer:
7) 8.94
8) 6.71
Step-by-step explanation:
for both questions, use pythagorean theorem

<u>Question 7:</u>

16 + 64 =
80 =

c = 8.94
<u>Question 8:</u>

36 + 9 = 
45 = 

c = 6.71
The answer is 4.782, so yes maria is correct:-)
Answer:
A = 120, P = 55
Step-by-step explanation:
Triangle
Area = (bh)/2
A = (20x12)/2
A =240/2
A = 120
Perimeter = a + b + c
to find c, use a^2 +b^2 = c^2
20^2 + 12^2 = c^2
400 + 144 = c^2
544 = c^2
c = about 23
20 + 12 + 23 = 55
