So firstly, what two terms have a product of 8x^2 and a sum of 9x? That would be x and 8x. Replace 9x with x + 8x: 
Next, factor x^2 + x and 8x + 8 separately. Make sure that they have the same quantity on the inside: 
Now you can rewrite the equation as 
Now using zero product property, solve for x:
<u>In short, the solutions are {-1,-8}, or C.</u>
1) angle 2 = angle 4
115 = 3x + 16
115 - 16 = 3x
99 = 3x
x = 33
2) angle 2 + angle 5 = 180 degrees
115 + angle 5 = 180
angle 5 = 180 - 115
angle 5 = 65 degrees
3) Angle 1 is equal to 120 degrees
0.15 with dash on top and the dash means its a repeating decimal and a repeating decimal is a decimal that repeats itself in this case it would be 0.1515151515 and so on
Answer:
128
Step-by-step explanation:
As they have added the same shape onto the top of the rectangle as they have taken away from the bottom, just do 16x8.
Well you see partition means to separate or divide. A line segment with end points a and b can be partioneded by another point by a given ratio, and a ratio is a comparison of two numbers. For other ratios besides 1:1 , it is necessary to determine the total number of parts that the line segment must be divided into. So in your case the point is 5:7 so you to determine the point that divides your line segment you just simply add the figure 5 a and the figure 7 together and you should end up with the sum of 12.
