Adding fractions with different denominators?
You need to change the denominators so they are the same ( by timesing them together) E.g. 1/7 1/2 7x2=14
Explain how solving inequalities is alike and different from solving equations?
Most of the steps are the same. The main difference is that if you multiply or divide both sides of an inequality by a NEGATIVE number, you must change the direction of the inequality sign (for example, change "less than" to "greater than").
How can two rectangular prisms have the same surface area but different volumes?
Yes, they can. They can also have the same surface area, but different volume.
How do you change the denominator?
Multiply the numerator and the denominator by the same number and you can change it to whatever number you need.
Can polynomials with the same graph have different roots?
False! If the graph is exactly the same, then the x-intercepts will be the same which implies the roots are them same. However, you can have the same roots and different graphs. So while the first statement is true, the converse if not.
