20+4x=76  subtract 20 from both sides

4x=56  divide both sides by 4

x=14

So he was driving at 55+14=69 mph

It's choice C as the root overhead bar goes over all of (x-7) and not just the x. So you have the correct answer. 

f(x) = x^4+7
y = x^4+7
x = y^4+7
y^4 = x-7
y = FourthRoot(x-7)

y = \sqrt[4]{x-7}

Simplify(5p^2-3)+ (2p^2-3p^3)
antiseptic1488 [7]
If you would like to simplify (5 * p^2 - 3) + (2 * p^2 - 3 * p^3), you can calculate this using the following steps:

(5 * p^2 - 3) + (2 * p^2 - 3 * p^3) = 5 * p^2 - 3 + 2 * p^2 - 3 * p^3 = - 3 * p^3 + 7 * p^2 - 3

The correct result would be - 3 * p^3 + 7 * p^2 - 3.
