Answer:
285
Step-by-step explanation:
9 = 7 + 2¹
13 = 9 + 2²
29 = 13 + 2⁴
285 = 29 + 2⁸
The sum of the given expression is 6b^2+8b-15
<h3>Sum of expression</h3>
Given the following expression
(6b^2+5)+(8b-20)
We are to take the sum. On expansion;
6b^2+5 + 8b-20
Collect the like terms
6b^2+8b +5 - 20
6b^2+8b-15
Hence the sum of the given expression is 6b^2+8b-15

Answer:
5.4
Step-by-step explanation:
Using the pythagorean theorem (a^2 + b^2 = c^2), we can do 2^2 plus 5^2, which is 4 + 25, which simplifies to 29. Now we have 29 = c^2
In order to find c (the hypotenuse), we need to take the square root of both sides to find c. Thus, c = sqrt 29 or 5.385...
