What is the value of the expression −3a+b2−10c

if a = 2, b = -4, and c = 7?

1 answer

To find the value of the expression, we substitute the given values of a, b, and c into the expression:

-3(2) + (-4)^2 - 10(7)

= -6 + 16 - 70

= 10 - 70

= -60

Therefore, the value of the expression -3a + b^2 - 10c, if a = 2, b = -4, and c = 7, is -60.
