what you learned and why it was important, how it is connected to other topics
1-power and exponents
i think the powers and exponents are the important part of our math 9 because we used them a lot in this year and next year too they are some different types of power and they are solving in different way .they are tracking you to do them wrong and if you make seance when you are solving them you could get a right answer.they also make your solving in better and easier way the number beside the real number in top of it is calling power means that number is a number that the another number get times to their self those times.and the number in a side calling base if.if in power we had a bracket too means we should times the brackets to whole number in brackets and the important part is that the number is negative or positive.
i think the next important thing is polynomials in math because we were using them a lot and the important thing is we should group the same things means the squares and Xes and the normal numbers . they are three different types of them that called binomials.monomial.trynomial.polynomials their differents are betwee how many terms that they have
3-symmetry and surface area
the surface area is important for those that want to be engineer or architect.but they are important for our math .the most important thing is do not forgot formula of them .surface area means solving how much is that a sides that we could see.
for the cube of rectangle we can solve the one side and then we can times it to two because the cube has a two same side and we do not need to solve to give anyone of them
4-linear equations and Inequalities
this unit is about finding X in equations
we could find the answer with help from our polynomials unit too because we can find the answer with the papers that we made in class.Above are linear equations with either one or two variables. There may be a set of linear equations each equation of which shares the same values of variables. Such set is known as a system of linear equationsLinear equations that contains one or more rational expressions are rational equations. To solve these linear equations, multiplying both sides of the equation by the lowest common multiple of the denominators. Then solve the equation by applying the same operations to both sides of it
5-scale factors and similarity
A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x. For example, doubling distances corresponds to a scale factor of two for distance, while cutting a cake in half results in pieces with a scale factor of one half
In two similar geometric figures, the ratio of their corresponding sides is called the scale factor. To find the scale factor, locate two corresponding sides, one on each figure
