How many terms are in a^2-ab+8b+b^2-1
DanielleElmas [232]
Remember that the terms of a polynomial are the parts of the polynomial separating by addition and subtraction; in other words, the parts separated by (+) and (-) signs. Knowing this, we can separate the terms of our polynomial:
a^2-ab+8b+b^2-1
- First term: a^2
- Second term: -ab
- Third term: 8b
- Fourth term: b^2
- Fifth term: -1

We can conclude that there are 5 terms in the polynomial a^2-ab+8b+b^2-1.

Please Help I Don't Understand.
lyudmila [28]

BE and CD are parallel, so the triangles ABE and ACD are similar. Then the following relation holds:

AE/AD = AB/AC

10/(10 + 8) = x/(x + 6)

Solve for x :

10 (x + 6) = x (10 + 8)

10x + 60 = 18x

8x = 60

x = 60/8 = 7/5
