Answer:
(f - g)(x) = 3x - 7
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
= 4x - 3 - ( x + 4 )
= 4x - 3 - x - 4
= 3x -7
Answer:
See explanation
Step-by-step explanation:
Ana started the work nicely by multiplying out factors to get:\
She multiplied correctly using difference of two squares to get:
Unfortunately: She made a mistake in multiplying she mistakenly got instead of . <em>She left out the coefficient of 2.</em>
Therefore the second step should have been:
The next step will now be:
This simplifies to
The square has 4 sides of the same measure.
If square SQUA has a side measuring 25 mm, it means side QU measures the same.
Also, if quadrilateral AQER is a square two, then its diagonals bisect each other, then QU is equal to UR.
Thus, QR measures:
The answer is 50 mm
