<span> x • (11x4 - 14x3 + 12)</span>
Let x be the number Henry is thinking of.
The number is doubled and got an answer of 4.
That means:
2 · x = 4
or
2x = 4
This is the equation when Henry doubled the number and got 4 as an answer.
Solve it by dividing both sides by 2.
2x ÷ 2 = 4 ÷ 2
x = 2
The original number Henry was thinking was 2.
Cheers!
If you would like to find g(2), you can do this using the following steps:
g(x) = x^2 - 5x + 7
g(2) = 2<span>^2 - 5 * 2 + 7 = 4 - 10 + 7 = 1
The correct result would be d. 1.</span>
