S = length of small side
M = length of medium side
L = length of long side
The triangle is scalene meaning that the three sides (S, M, L) are all different. If any two sides were equal, then we'd have an isosceles triangle. If all sides were the same, then the triangle would be equilateral.
"The longest side is twice that of the shortest side" tells us that L = 2*S
The longest side is given to be 6.2 cm, so L = 6.2 and we can find S to be...
L = 2*S
6.2 = 2*S
2*S = 6.2
S = 6.2/2
S = 3.1
The longest side is 6.2 leads to the shortest side being 3.1
Add up the three sides and set that sum equal to the perimeter 14.5
(short side) + (medium side) + (long side) = perimeter
S + M + L = 14.5
3.1 + M + 6.2 = 14.5
M + 9.3 = 14.5
It's not clear where your teacher wants you to stop, so this might be a good place. If you wanted, you can isolate M by subtracting 9.3 from both sides
For this you would want to break this fgure up with familar shapes. You can do two triangles and one big rectangle.
First triangle:
(3)(2)(1/2)= 3 feet squared
Second Triangle:
(3)(4)(1/2)= 6 feet squared
Rectangle:
(11)(3)= 33 feet squared
Now you add:
33+3+6= 42 feet squared
So, for this hole you will need 42 feet squared of outdoor carpet
4(9) + 3s = 75
36 + 3s = 75
3s = 39
s = 13
Answer:
7
Step-by-step explanation:
form a proportion
12/2=42/x
cross multiply
12x=84
x=7
SIMPLIFY LIKE TERMS. CIRCLE ALL THE TERMS WITH X'S AND SQUARE THE ONES WITH Y'S SO YOU DONT GET CONFUSED.
SO THE ANSWER IS
-3X -Y
BAM DONE
