Split the second term in 5x^2 + 23x + 26 into two terms
5x^2 + 13x + 10x + 26
Factor out common terms in the first two terms, then in the last two terms
x(5x + 13) + 2(5x + 13)
Factor out the common term; 5x + 13
<u>(5x + 13)(x + 2)</u>
The mean is 62 (496/8=62)
The median is 63 (52,52,52,62,64,69,69,76 take the two middle numbers and find the average 62+64/2=63)
The mode is 52 (there are three 52's)
Answer:
I can't exactly draw this out on this website, but I can tell you how to do it:
First, solve the inequality so it resembles a function:
7x - y ≥ 14
-y ≥ -7x + 14
y ≤ 7x - 14 (Both side multiply by -1)
Then, graph y = 7x - 14
- Draw a straight line (Don't do the dotted lines because it's not > or <)
- Here's a couple of points to get started: (0, -14), (1, -7)
Finally, because y is less than/equal to 7x - 14, shade in the area under/below the line(where the y-values are smaller).

Answer:
54
Step-by-step explanation:
The given number to be increased = 36
The percentage by which the number is increased = 50%
In increasing a number by a percentage, we find the value of the percentage increase of the number and add to the number as follows;
50% of 36 + 36 = 50/100 × 36 + 36 = 54
Second method
The find the number obtained by increasing a number by a given percentage 'x', we add 100 to the give percentage and multiply the result by the number and hen divide the final result by 100 as follows;
36 increased by 50% = (100 + 50) × 36/100 = 54
