By Interpret expressions that represent a quantity in terms of its context. Interpret parts of an expression, such as terms, factors, and coefficients. Interpret complicated expressions by viewing one or more of their parts as a single entity.
In general, the scalar multiple of k times u,<span> is this:
</span>
So, here's how we find
The answer is <span><span>(6,12).</span></span>
Multiply it out
x^2 + 4x -8x -32
Combine like terms
x^2 -4x - 32
The answer is 25 because of the Pythagorean theorem. 49+576=625 625 squared=25
