3) TRUE / FALSE:
The greatest common factor of the terms 12x5 and 36x3 and 66x” is 6x3
4)
TRUE / FALSE:
We know that parabola formed by the quadratic equation y = -3x2 – 7x + 1 will open
down because the coefficient – 7 is less than 0.

Step-by-step explanation:

3) Because 12x5=60, and 18 DOES NOT go into 60 evenly.

60/18= 3.33   ->   Not a whole number

4) Because the -7 is not what determines the parabola to be up or down. If it were a +7 instead of -7, it still would make the parabola open down.

-THE ONLY WAY the parabola would open up... is if you change the -3x^2 into a positive (3x^2)

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
