Jonestown High School has a soccer field whose dimensions can be expressed as 7y2 and 3xy. What is the area of this field in terms of x and y?
Since the area of the soccer ?eld would be found through the formula A = length × width, multiply the dimensions together: 7y2 × 3xy. Use the commutative property to arrange such as variables and the coef?cients next to each other: 7 × 3 × x × y2 × y. Multiply: remember that y2 × y = y2 × y1 = y2+1 = y3. The answer is 21xy3.
Consider the following multiplication in decimal notations: (999).(abc)=def132 ,determine the digits a,b,c,d,e,f. solution) a=8 b=6 c=8 d=8 e=6 f=7 In other words, 999 * 877 = 8

What is Angle Pairs? Two angles are adjacent angles if they have the same vertex and share one side. Vertical angles are a pair of nonadjacent angles formed by two intersecting
I've termed this section as Intervals of Validity since all of the illustrations will involve them. Though, there is many more to this section. We will notice a couple of theorems
