The answer is 10 hoped that helped
(5x+15)(6x-10)
= 30x^2 + 30x - 50x - 150
= 30x^2 - 20x - 150
2(5-n) can be an expression of "twice the difference of 5 and n".
Answer:
x=30° y=4
Step-by-step explanation:
cross multiple
5y=8(2.5)
5y=20
divide 5 by 20
and you should y=4
since the polygons are similar x should have the same degrees as the bigger polygon
You'll have to adapt this problem statement to Brainly, as Brainly does not have the Segment Tool available.
"starts with 90 pencils" implies that the y-intercept is (0,90).
"gives away 15 pencils" implies a slope of -15 pencils per unit of time
Thus, the # of pencils Jabian still has is P(x) = 90 - (15 pencils / time unit)x
