U=2 Becuase you have to get u bye itself
Using cosine law.
b= sqrt(38^2 + 18^2 - 2(38)(18) Cos 36)
using calculator solve.
b = sqrt (1444 + 324 - 1106.75)
b = 25.75
Answer:
5
Step-by-step explanation:
First multiply 7 and 4
7 * 4 = 28
Then divide 140 by 28
140/28 = 5
Height is 5
A = 9y+3xy
take 3y as a common factor:
a = 3y(3+x)
this is the simplest form of this expression.
