Answer:
10
Step-by-step explanation:
4x+8+3x+12=90
x=10
this is the solution hope it's helpful
It is B just use a calculator hope it helped
F(19)= (3/(19+2)) - sqrt(19-3)
= (3/21) - sqrt(16)
= (1/7) - 4
= (1/7) - (28/7)
= -27/7
= - 3 6/7
at least 4 different angles are present
first divide 90 by 4 to see how many words per minute
90 ÷ 4 = 22.5
then multiply 22.5 by 10 to get your answer
so your answer is;
225 words per 10 minutes
