Answer:
Step-by-step explanation:
The polynomial given is:
<em><u>Grouping the first 2 terms together and the last 2 terms together and taking common, we have:</u></em>
This is the complete factorization.
Answer:
Angle y measures 130 degrees
Step-by-step explanation:
Notice that the angles marked as "2x+18", and "4x-14" must be equal angles since they are generated on the same sector (top right) of the parallel lines by the transverse line "b".
Then by finding the value of "x" we can deduce the value of the actual angle these two angles measure:
Now, we can find the actual value of these two angles, we use for example the first expression:
Top-right angle =
Now, if these two angles measure , then angle "y" (which is the supplementary angle (angle which added renders ) for them, must equal

Answer: 30</h3>
==========================================================
Explanation:
Refer to the drawing below. I have a 2 by 5 grid of squares. So there are 2*5 = 10 squares total.
Four of those squares are shaded blue to represent the fraction
If Susan used 4 blue tiles (instead of 12), then she'd have 10 tiles total. This would mean 10 would be the answer.
However, she's using 12 blue tiles. The jump from 4 to 12 is "times 3". So we'll need to multiply that 10 by 3 as well.
10*3 = 30
If Susan uses 12 blue tiles, then she has 30 tiles total.
Notice that the fraction is the same as after multiplying both top and bottom by 3.
If you wanted, you can split a round cake into 10 equal slices. If a person eats 4 slices, then that represents the fraction . Now imagine splitting each of those initial ten slices into three smaller pieces. If you manage to do so, then you'd have 30 very small slices. The four that the person ate would have effectively eaten 12 very small slices. So this is another way to see how . Personally, when it comes to fractions, I prefer using a grid of squares because it's a bit tricky sometimes to divide up circles perfectly.

are you talking about like 24/7 ? or you mean like divide 24÷7 ?
