A cube's surface is made of 6 squares, (you can count it there are 6 faces :) ). A square's surface area is  { x }^( 2 )  x is length of one edge. So we will multiply { x }^( 2 ) by 6 to find the total surface area. The x is given 8, let's plug it in the formula.

6{ x }^( 2 )\n \n 6\cdot { 8 }^( 2 )=6\cdot 64=384\quad square\quad units

6x^2-4xy-15xy+10y^2 factor by grouping

We will need to split the middle term and use the grouping method. To do this multiply the coefficient of the first term (6) against the coefficient of the last term (10):

6 * 10 = 60
Factors of 60 = +-(1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60)

From the list of factors find two numbers that when added together give -19 and when multiplied together give 60. -15 and -4 added together give -19 and multiplied together give 60 so split the middle term by rewriting these values back into the expression:

6x^2 - 15xy - 4xy + 10y^2

Now use the grouping method, take out the highest common factor between the two sets of terms:

3x(2x - 5y) - 2y(2x - 5y)

Group the outside terms:

(3x - 2y)(2x - 5y)


Answers
6 = -3*-2
10 = 5*2
5*3+2*2=19
thus
(2y-3x)(5y-2x)

Which equation represents the graph of the linear function?A. y= -1/3x+1
B.y=-3x-1
C.y=3x+1
D.y=-3x+1

Answers

The answer is D because the y intercept is a positve one, and when you find the slope, it is -3. To find the slope, you can either pick two points on the graph and do y1 -y2 over x1-x2, or you can count the slope on the graph.

Solve 2a + 21 = 8a - 9, step by step

Answers

2a + 21 = 8a - 9

Combine like terms. 

2a + 21 = 8a - 9
-2a          -2a

21 = 6a - 9 
+9          +9

30 = 6a
6a/6 = 30/6
a = 5

Answer: a = 5
