Evaluate 3p^2 + 7 (3 times p to the second power plus 7), when p = 4

55

Step-by-step explanation:

3p²+7

= 3 ×4²+7

= 3× 16+7

= 48 +7

=55

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
