Answer:
C. Four less than seven times quantity of a number plus twelve.
Step-by-step explanation:
We can see from the given expression that 4 is subtracted from 7(x+12). The term used to describe subtraction is less. So, it is 4 less than 7(x+12).
We can clearly see that the first term is x and x can take any value.
So the whole expression will be four less than seven times quantity of a number plus twelve.
Hence option C is the correct answer ..
( x - 3i√2)(x + 3i√2)
solve x² + 18 = 0
x² = - 18 ⇒ x = ±√- 18 = ±3i√2
factors are ( x - (3i√2))(x - (-3i√2))
x² + 18 = (x - 3i√2)(x + 3i√2)
2.5 + 4.25x
2.5 + 4.25(5) = 2.5 + 21.25
= 23.75
Hope this help
