If you would like to solve the equation b^2 + 9 * b + 18 = 0 for the variable b, you can do this using the following step:

b^2 + 9 * b + 18 = 0
(b + 3) * (b + 6) = 0

Result:
1. solution: b = - 3
2. solution: b = - 6

blsea [12.9K]

Answer:

12 is mean 11 is median range is 14

Step-by-step explanation:

For the Mean

Add all the numbers up

16 + 9 + 20 + 10 =55

12 + 6 + 8 + 15 = 41

55 + 41 = 96

There are 8 numbers so we divide by 8

96/8 = 12

Range is Smallest number minus biggest so 20 - 6 = 14

A 13-foot ladder leans against the side of a house with its base 3 feet from the house. Use the Pythagorean Theorem to approxima

scZoUnD [109]

Answer: 12.65 ft

Pythagorean theorem is $a^{2}$ + $b^{2}$ = $c^{2}$

So, $a^{2}$ + $3^{2}$ = $13^{2}$

169 - 9 = 160

$\sqrt{160}$ is 12.65.

Hope it helps.
