It is always negative, because it keeps going down on the number line. Say it is negative 8 minus 5, it would be negative 13, because it adds to the negatives, so it would go deeper into the negatives.
AREA = 2428
c= 76
angle A= 85 deg
angle B= 42 deg
For the volume of triangular prism, volume = 0.5xaxbxc
=0.5x10x7x6
=210cm^3
Answer:
14
Step-by-step explanation:
12:6=2
12+2=14
so her brother it's 14 years old
The dimensions given when you have a triangle is the base and height of the triangle. The formula for the area is
A = 0.5bh
The unknown here is h. We can determine that from the cost of mulch that covers the whole area of the triangle. The equation would be:
4A = 33
Substituting A = 0.5*5.5*h = 2.75h to the equation:
4(2.75h) = 33
11h = 33
h = 33/11
h = 3 feet
