Answer:
x² -25
Step-by-step explanation:
(x +5)(x -5) = x(x -5) +5(x -5) = x² -5x +5x -25 . . . . . 5x terms cancel
= x² -25
_____
This is an example of the factoring of the difference of squares:
(a+b)(a-b) = a²-b²
400 divided by the 2 teams would be a unit rate of $200 per team
9514 1404 393
Answer:
B = 13
Step-by-step explanation:
The tangent and cotangent are equal when the angles are complementary.
(3B +35) +(2B -10) = 90
5B = 65
B = 13
___
<em>Check</em>
For B=13, the angles are 3B+35 = 39+35 = 74, and 2B-10 = 26-10 = 16. Both are acute angles.
The final answer for this question would be.....
8.8n^2+16n+0.1
