2/5m - 4/5 - 3/5m...combine like terms
-1/5m - 4/5
Answer would be 58.5 yd^2 .
You should take the base of the triangle multiplied by the height.
Formula: 1/2×base×height
In this case, you know that base is 13yd and height is 9 yd.
So, apply the formula.
Area = 1/2(13yd)(9yd) = 58.5 yd^2
*Do not include the " invisible length as it is not part of the actual triangle.
*Do not include 32yd as it is a hypotenuse and not a base. Hypotenuse is a side that is opposite a right angle triangle.
9/20
the numbers that would satisfy this are 15,16,17,18,19,20, 1,2,3
so there are 9/20
Answer:
(3 * 2.50 + 8 * 1.25) d =
3*2.50 d + 8*1.25 d
or
7.50 d + 10 d
