If B = -p + 10p^2 and C = 2p + 7, find the expression that equals B + 3C in standard form
To find the expression that equals B + 3C, we simply substitute the given expressions for B and C into the equation:
B + 3C = (-p + 10p^2) + 3(2p + 7)
= -p + 10p^2 + 6p + 21
= 10p^2 + 5p + 21
Therefore, the expression that equals B + 3C in standard form is 10p^2 + 5p + 21.
