Answer:
Step-by-step explanation:
to divide fractions you take the second one, flip it and multiply.
So 8/17 times 20/9 160/154 which is equivalent to 80/77 or 1.039

Answer: Choice B</h3>
Explanation:
Choice A is a reflection. Choice C is a rotation. Reflections and rotations are isometries because they preserve the same shape and size of the original figure. Translations are the third type of isometry.
Choice B is not an isometry. It looks like an extra point is added along with extra line segments. The before and after figures are completely different.
The area of the two top triangles is
.. 2 * (1/2)*(9.5 in)*(7 in) = (9.5 in)*(7 in)
The area of the bottom two triangles is
.. 2 * (1/2)*(9.5 in)*(12 in) = (9.5 in)*(12 in)
Then the total area is
.. (9.5 in)*(7 in) +(9.5 in)*(12 in)
.. = (9.5 in)(7in +12 in)
.. = (9.5 in)(19 in)
.. = 180.5 in²
Answer:
x2 • (x2 - 32772)
Step-by-step explanation:
step 1: ((x4) - 22x2) - 32768x2
step 2: Pull out like factors :
x4 - 32772x2 = x2 • (x2 - 32772)
Factoring: x2 - 32772
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 32772 is not a square !!
Ruling : Binomial can not be factored as the difference of two perfect squares.
