Evaluate a + 4 a+4a, plus, 4 when a = 7 a=7a, equals, 7.
1 answer:
<em>When evaluating then we get that the expression is 11</em>
As I understand the expression is the following:
Let's call, that expression as
So we are asked to find the value of the expression when . In other words, we need to substitute
, so:
So <em>when evaluating then we get that the expression is 11</em>

we know the segment QP is an angle bisector, namely it divides ∡SQR into two equal angles, thus ∡1 = ∡2, and ∡SQR = ∡1 + ∡2.
The cross product of two vectors gives a third vector 
that is orthogonal to the first two.
Normalize this vector by dividing it by its norm:
To get another vector orthogonal to the first two, you can just change the sign and use
