Answer:
C, 7 1/2
Step-by-step explanation:
12 is 2/3 of 18, therefore 5 is 2/3 of something, so you divide 5 by 2/3 which is 15/2 which is 7 1/2
= ( 3x² + 3x + 5 ) ( 6x + 4 )
= 18x³ + 18x² + 30x + 12x² + 12x + 20
= 18x³ + 30x² + 42x + 20
Answer:
87.5
Step-by-step explanation:
By completing the square,
y
=-14x^2+70x
=-14(x^2-5x)
=-14(x-5/2)^2+175/2
the max. height=175/2
i.e. 87.5
The answer is C. It is nonlinear because the increase in the “total house built” compared to the increase in the “months passed” does not show a constant rate of change.
False
Because the left side comes out to a sum of 40 while 15-7 equals 8 and 24 times 3 equals 72 72 plus 8 equals 80 divided by 2 equals 40 and 8 times 9 equals 72 plus 6 equals 78 plus 6 equals 84
