Answer:

\huge\boxed{\frac{2}{15} \text{        yards}}

Step-by-step explanation:

We have a board that is \frac{2}{3} yards long. If we want to cut the board into 5 <em>equal pieces</em>, we must divide \frac{2}{3}  by 5.

\frac{2}{3} \div 5

5 is the same thing as \frac{5}{1}, so:

\frac{2}{3} \div \frac{5}{1}

To divide a fraction by a fraction, we multiply by the reciprocal.<em> </em>This means we take the reciprocal of \frac{5}{1} and multiply the two fractions.

The reciprocal of \frac{5}{1}  is \frac{1}{5} - we swap the numerator and denominator.

\frac{2}{3} \cdot \frac{1}{5}

Multiply the numerator and denominators to get our final fraction:

2\cdot 1 = 2\\3 \cdot 5 = 15\\\\\frac{2}{15}

Hope this helped!

Part A: Factor x2y2 + 6xy2 + 8y2. Show your work. (4 points) Part B: Factor x2 + 8x + 16. Show your work. (3 points) Part C: Fac
skad [1K]

Answer:

Part A : y²(x + 2)(x + 4)

Part B: (x + 4) (x + 4)

Part C: (x + 4) (x - 4)

Step-by-step explanation:

Part A: Factor x²y²+ 6xy²+ 8y²

x²y²+ 6xy²+ 8y²

y² is very common across the quadratic equation , hence

= y² (x² + 6x + 8)

= (y²) (x² + 6x + 8)

= (y²) (x² + 2x +4x + 8)

= (y²) (x² + 2x)+(4x + 8)

= (y²) (x(x + 2)+ 4(x + 2))

= y²(x+2)(x+4)

Part B: Factor x² + 8x + 16

x² + 8x + 16

= x² + 4x + 4x + 16

= (x² + 4x) + (4x + 16)

= x( x + 4) + 4(x + 4)

= (x + 4) (x + 4)

Part C: Factor x² − 16

= x² − 16

= x² + 0x − 16

= x² + 4x - 4x - 16

= (x² + 4x) - (4x - 16)

= x (x + 4) - 4(x + 4)

= (x + 4) (x - 4)

Find the GCF of the terms of the polynomial.
-BARSIC- [3]
<h3>Answer:   2z^3</h3>

====================================================

Explanation:

The GCF of the coefficients {6, -42, 14} is 2 as it is the largest factor found in each of the three values.

----------

For the variable portions, we can

  • write z^5 as z^3*z^2
  • write z^4 as z^3*z^1
  • write z^3 as z^3*1

Each time we see z^3 show up, so this is the largest common factor among the three variable terms.

----------

The two results we got were 2 and z^3

Putting the two results together, we end up with the overall GCF of 2z^3
