Start with 2. Then subtract from it (2x - 7)^2.
2 - (2x - 7)^2

Answer:
1176
Step-by-step explanation:
First, calculate the volume as if it was a full rectangle.
Volume formula:
length x width x height
16 x 6 x 21 = 2016
(this is the volume if this was a full rectangle)
Now to calculate the size of the missing part we do the same thing
10 x 6 x 14 = 840
To work out the volume of this shape, we need to subtract the volume of the missing part from the volume of the rectangle
2016 - 840 = 1176
I hope this helped :-)
Answer:
3(x + 12)(x + 2)
Step-by-step explanation:
Given
3x² + 42x + 72 ← factor out 3 from each term
= 3(x² + 14x + 24) ← factor the quadratic
Consider the factors of the constant term (+ 24) which sum to give the coefficient of the x- term.
The factors are + 12 and + 2, since
12 × 2 = 24 and 12 + 2 = 14, thus
x² + 14x + 24 = (x + 12)(x + 2) and
3x² + 42x + 72
= 3(x + 12)(x + 2) ← in factored form
