(x+2)(x+8) = x^2 +10x +16
(x^2 + 10x + 16)(x-1) = x^3+9x^2+6x-16, so the other dimension is x-1
<h2>

i hope this helped. please give brainliest if it did!
Answer:
a = 35°; b = 50°; c = 85°; d = 30°
Step-by-step explanation:
a = 35° because a + 80 + 65 = 180.
b = 50° because b+ 35 + 95 = 180.
c = 85° because c + 95 = 180.
d = 30° because d + 85 + 65 = 180.
He has 20 pencils.
The ratio in the problem is 4 pens to 5 pencils meaning for every 4 pens there are 5 pencils.
So take this into mathematics 16pens/4pens = 4
5pencils * 4 is equal to 20 pencils
the ratio still works and it is still 4 to 5 so the answer is 20...pencils.
Answer:
p and q are parallel to each other and l, m, and n are all parallel
Step-by-step explanation:
because it tells us they make right angles we know all the lines are going straight therefor they will not intersect with each other
