For this case we have the following polynomial:

We make the following change of variables:

Rewriting we have

Factoring the second order polynomial we have:

Then, returning the change we have:

Finally, we factor the expression in the parentheses of the second term:

Answer:
the completely factored form is:

You can figure out what four times eight is by adding eight and eight(16) and doubling it (32)
Answer:
160 cm × 120 cm
Step-by-step explanation:
this means 1 cm turns into 20 cm.
so, 8 cm × 6 cm becomes
8×20 = 160 cm × 6×20 = 120 cm
Answer:
-99.12525
Step-by-step explanation:
Perimeter: 36.84 feet
Let’s start with the easy part...all the rectangle pieces 6 x 3 = 18 feet
We know from subtracting the rectangle length (6ft) from the total length (12 ft) that the diameter of the circle is 6ft.
Circumference = diameter x pi
= 6 x 3.14 = 18.84
We have the circle split into 2 halves, but the circumference remains the same
18 + 18.84 = 36.84
