Answer:
12.5 in by 6 in
Step-by-step explanation:
The dimensions would be 250 / 20 = 12.5 inches by 120 / 20 = 6 inches.
Answer:
3(2x^2-3x+14)
Step-by-step explanation:
6x^2-9x+42
All three terms have a common factor of 3
3(2x^2-3x+14)
Now let's focus on 2x^2-3x+14 and bring down the factor 3 later
so a=2
b=-3
c=14
Let's try to find two factors for ac that multiply to be a*c and add up to be b.
ac=28
b=-3
-----
ac=7(4)=14(2)=8(2)
Even if I made these pairs with both negatives nothing would give me -3
So you can only go as far as 3(2x^2-3x+14)
Here is another thing to help you if you have ax^2+bx+c and b^2-4ac<0 then it can't be factored (over reals)
First add 5 to 16, so -3x=21
then divide by -3, so the answer is
x= -7
Answer:
9 times as many as 3 is 27.
