Answer: 23
Step-step by explanation:
w(w+4)=437
w^2+4w-437=0
(w+23)(w-19)=0
w=19,-23
w<19
l<23!!
If you would like to solve the equation k / 2 + 9 = 30, you can calculate this using the following steps:
k / 2 + 9 = 30
k / 2 = 30 - 9
k / 2 = 21 /*2
k = 21 * 2
k = 42
The result is 42.
Answer:
c = 15 meters
Step-by-step explanation:
This is solveable using the Pythagorean Theorem,
let's say a = 9 and b = 12,
a^2 + b^2 = c^2, so
9^2 + 12^2 = 225 then,
sqrt(225) = 15, so c = 15 m
