Answer:
We actually can't answer this because we need at least one angle in the triangle. However, the unknown length has a range. And the range is:
3<C<9. This is from the triangle inequality.
If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate.
4/5 = ?/45
5 times 9 = 45.
What we do to the denominator must be done to the top, as well. 4 times 9 = 36.
So, the missing number is 36.
First write the question:
3a^2 + 4b^2
Substitute:
3 x (2^2) + 4 x (3^2)
Simplify:
(3 x 4) + (4 x 9)
Simplify again:
12 + 36
Answer:
48
