2y3 - 27 + 5y2 + (25 / 5)
what is the value of the expression when y = 2?
a)14
b)0
c)7
d)68

The correct option is A

Step-by-step explanation:

The expression is

2y3 - 27 + 5y2 + (25 / 5)

Substitute the value of y=2 in the expression:

=2(2)³-27+5(2)²+(25/5)

We know that 2³ means multiply 2 three times

2³= 2*2*2=8

Likewise 2²=2*2=4

=2(8)-27+5(4)+(25/5)

=16-27+20+25/5

Now take the L.C.M which is 5

=80-135+100+25/5

Solve the values in the numerator:

=70/5

=14

Thus the correct option is A

f(x) = y

f(-3) = -5

step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
