For these ones I just play around with what I can divide 84 by to equal -33 in the middle. I decided to divide 84 by 4 because it was an even number. 

84/4=21

21+ (3*4)= 33

Answer: (x-4)(3x-21)

Answer:  The factors of the given expressions are 3, (x-7) and (x-4).

Step-by-step explanation:  We are given to find the factors of the following quadratic expression :

E=3x^2-33x+84~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To find the factors of the given expression, we need to find two integers with sum -33 and product 252.

From (i), we have

E\\\\=3x^2-33x+84\\\\=3x^2-21x-12x+84\\\\=3x(x-7)-12(x-7)\\\\=(x-7)(3x-12)\\\\=3(x-7)(x-4).

Thus, the factors of the given expressions are 3, (x-7) and (x-4).

None of this makes sense
Elena L [17]

The volume of the cone is:

V=Sb×h/3=(pi×r²)×h/3, where Sb is the area of the base (circle of radius r) and h is the height.

V=pi×r²×h/3=pi×1.5²×5/3=11.775in³

The closest indicated value is the first one, 11.78in³

Answer:

Below in bold.

Step-by-step explanation:

Area = altitude * base

3.   6.2 * 6

=  37.2 cm^2.

4.  0.12 * 0.24

= 0.0288 m^2.

5. 32 * 0.4

= 12.8 m^2.

The bench costs $450.
You first need to subtract the difference between the garden table and the bench from the total so they are equivalent, and then divide by two to find what the bench is on its own.
(The garden table costs $536, by the way. To find that, you just need to add its half of 900, 450, to the 86 you subtracted initially.)
Tell me if this doesn’t make sense, it’s sort of hard to explain!
