The answer=>
For this,we need to know what's Middle splitting method
- In order to factorize x² + bx + c we have to find numbers p and q such that p + q = b and pq = c. After finding p and q, we split the middle term in the quadratic as <em><u>px + qx and</u></em> get desired factors by grouping the terms.
Step-by-step explanation:

i.e
Alpha= Beta = 4
15 x 3= 45 so 3 hours is the answer
Answer:
out of 36 rolls, 15 were positive. 15/36 simplified is 5/12
When you want to find the slope of the perpendicular line, all you have to do is flip the known slope upside down and make it negative. You know that

slope is 3 and you know

is perpendicular. So, just flip 3 upside down into

and then make it negative,

. If you look at the coordinate grid, you can see that

crosses the y-axis at 4. When you put those into slope-intercept form you get

x + 4.
