Girardo uses the following steps:

Step 1 Add 4 negative x-tiles to both sides
Step 2 Add 1 negative unit tile to both sides
Step 3 The solution is

Which step could be adjusted so that Gerardo's final step results in a positive x-value?
In step 1, he should have added 4 positive x-tiles to both sides.
In step 1, he should have added 3 negative x-tiles to both sides.
In step 2, he should have added 4 negative unit tiles to both sides.
In step 2, he should have added 1 positive unit tile to both sides.

B or In step 1, he should have added 3 negative x-tiles to both sides.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,
