so what you do is
a^2-a-20
see, the number in front of the a^2 is 1, so now we do
look at the number infront of the a and the number at the end
-1 and -20
whhat 2 numbers multiply to get -20 and add to get -1
trial and error
-20+1=-19, nope
-10+2=-8 nope
-5+4=-1, yes
(a-5)(a+4) is factored
Answer:
Olivia will have only 4 blooms when she adds no fertilizer.
Step-by-step explanation:
Olivia is in the job of growing roses and keeps record of the amount of fertilizer (x, in ounces) she adds to the soil and the number of blooms (y) each rose bush has.
Now, the relation between x and y is given by the linear equation, y = 1.345x + 4.
Now, from x = 0, y value will be 4.
Therefore, Olivia will have only 4 blooms when she adds no fertilizer. (Answer)
If Ben reads 8 pages in 12 minutes, we can write it like this 8pages/12minutes.
If you want to know how many he reads in one minute, divide both values with 12, because we know for 12 minutes how many pages he reads, so:
8/12 pages per 12/12minutes = 2/3 of a page per minute.
Hope this helps!
Answer:
The measure of the angles in degree is 57.5 degrees
Step-by-step explanation:
If two angles are congruent, they are equal in value
Let the number be x
2x + 3 = 3x-54.5
Thus;
3x-2x = 54.5 + 3
x = 57.5
