Answer:

3(-x^2-6x+4)

Step-by-step explanation:

-3x^2 - 18x + 12

-3x^2 - (2 x 3^2) x + 2^2 x 3

3 (-3x^2 over 3 - 2x3^2 times x over 3 + 262 x 3 over 3)

3(-(x^2) - (2 x 3^2-1 times x) +2^2

3(-x^2 - (2 times 3x) +4)

3(-x^2-(6x) + 4)

3(-x^2 - 6x + 4)

Martin wants to ship a souvenir baseball bat that is 16 inches long in this box.
stich3 [128]

Answer:

Step-by-step explanation:

Remark

The first job is to find the diagonal along the bottom. Pretend that the sides and top do not exist for just a moment.

Givens

It becomes a Pythagorean problem.

a = 12

b = 9

c = ?

Solution

a^2 + b^2 = c^2

144 + 81 = c^2

c^2 = 225

sqrt(c^2) = sqrt(225)

c = 15

Remark

Now you look at the diagram again, a little more closely this time.

The diagonal that you want is from the lower right to the upper closest left.

c = 15

d = 8

e = ?

e^2 = c^2 + d^2

e^2 = 15^2 + 8^2

e^2 = 225 + 64

e^2 = 289

e = 17

The shipping box is large enough

Note

There is one think you can note

You can do this entire problem in one step

a = 12       b = 9     c= 8

a^2 + b^2 + c^2 = diagonal from lower right to upper left^2

12^2 + 9^2 + 8^2 = diagonal^2

144 + 81 + 64 = diagonal ^2

289 = diagonal^2

diagonal = 17 just as it did before.
