Answer:
36
Step-by-step explanation:
Given
x² + 12x = 11
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = 11 + 36
(x + 6)² = 47
I think the answer is 66. But I'm not sure just try and see...!
What you are doing is called cross multiplication. You have to multiply the top of the first fraction by the bottom of the second fraction. 1 x 378, which equals 378. Then you multiply the bottom of the first fraction by the top of the second fraction. 250 x X. 250x=378. You then have to solve for x or divide 378 by 250. The answer to 378 / 250 = 1.512. But the instructions want you to round to the nearest tenth and that is the first decimal place. Your answer is 1.5.
