Hi Starina,
I don't want to answer the question for you since you should be able to do this. But let me give you a useful way to think about it. 332 is 3 hundreds plus 3 tens plus 2 ones. 23 is 2 tens plus 3 ones. If I told you that I had 4 apples and 5 oranges in one...

Hi Maralyn,
Students often find this kind of problem hard because they have learned the FOIL (First, Outer, Inner, Last) method for simplifying problems like (x + 2)(x - 5) and don't know how to extend the FOIL method to problems like this one that have more than two terms in one or both...

Hi Valerie,
It would be helpful if you could repost with parentheses to show clearly how the various parts were grouped. For instance, were you actually given log2(x4 * sqrt(y) / z3)? Assuming that is the case, you would want to convert the expression inside the log so that all factors...

Hi Alexa,
I believe you're talking about the formulas that relate various segments of chords, secants, and tangents that intersect a circle and each other. There are also formulas for angles between chords, secants and tangents in terms of the lengths of arcs of the circle. You should...

Hi Angel,
Here is one way of solving this. The diagonal AC divides the rectangle into two triangles ABC and ACD. Let's focus on triangle ABC. We're told that the diagonal AC bisects angles A and C. But all the interior angles of a rectrangle are 90ยบ. So, the angles...

Hi Maureen,
It is unclear from your question whether you are just being asked to factor these expressions or to solve equations in which they are set equal to 0. Either way, we need to factor them. So, I'll show you how to do that and then how to solve the equations if they were...

If written exactly as shown, then no. But 50.1 x 103 would be correct scientific notation and that is probably what you were really asking about. In normalized scientific notation, the first number is selected to have an absolute value between 1 and 10. So, to write this...
