Need a little help with these problems:
1. (Solve equation for the given variable) ax + by + c = 0 for x 2. (Express answer in simplest form in terms of the given variable) The base and height of a triangle are consecutive odd integers, and the height exceeds the base. If the base is B cm, find the area of the triangle. -------- Can anyone tell me how to do these please?? |

The first question is totally correct, but for the second one, instead of doing square then halving it, I would just directly plug it into the triangle equation as:
b(b+2) -------- 2 the simplified version is right, but be careful how you write that cuz for a sec i thought it was b2, not b squared.... also depending on how your teacher likes it, I'd simplify it as B [ (b+2) /2 ] |
