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 ...
