Answer:

C  89a + 2c)

Step-by-step explanation:

The largest factor of both 8 and 16 is 8.  So, 8 = GCF

factor out an 8 and you get 8(a + 2c)

To check if you are correct, multiply and see if you get what you started with.

The width of a rectangular rug is 4 1/4 inches longer than twice its length. If the perimeter of the rug is 56 1/2 inches, which
olga_2 [115]

The question requires calculating the perimeter of the rectangular r ug

The equation which represent the situation is 113/2 = 6x + 34/4 and length is 8 inches and width is 20 1/4 inches

Given:

let

length of the rectangular r ug = x inches

Width of a rectangular r ug = <em>(2x + 4 1/4) inches</em>

Perimeter of the r ug = 56 1/2 inches

<em>Perimeter of the r ug = 2(length + width)</em>

56 1/2 = 2{x + (2x + 4 1/4)

113/2 = 2(x + 2x + 17/4)

113/2 = 2(3x + 17/4)

113/2 = 6x + 34/4

113/2 - 34/4 = 6x

(226-34) / 4 = 6x

192/4 = 6x

48 = 6x

divide both sides by 6

x = 48/6

x = 8 inches

So,

length of the rectangular r ug = x inches

= 8 inches

Width of a rectangular r ug = (2x + 4 1/4) inches

= 2(8) + 4 1/4

= 16 + 4 1/4

= 20 1/4 inches

Therefore, the equation which represent the situation is 113/2 = 6x + 34/4 and length is 8 inches and width is 20 1/4 inches

Please help asap, brainliest,thanks, and 50 points. Thank you soooo much! &lt;3
Anuta_ua [19.1K]

Answers:

1) x^{8} y^{8}

2) y^{3} \sqrt{y}

3) 5x^{4} \sqrt{6}

4) \sqrt{7}

5) \frac{\sqrt{z}}{z}

Step-by-step explanation:

1) \sqrt{x^{16} y^{36}}

Rewriting the expression:

(x^{16} y^{36})^{\frac{1}{2}}

Multiplying the exponents:

x^{\frac{16}{2}} y^{\frac{36}{2}}

Simplifying:

x^{8} y^{8}

2) \sqrt{y^{7}}

Rewriting the expression:

\sqrt{y^{6} y}=(y^{6} y)^{\frac{1}{2}}

Multiplying the exponents:

y^{\frac{6}{2}} y^{\frac{1}{2}}

Simplifying:

y^{3} y^{\frac{1}{2}}=y^{3} \sqrt{y}

3) \sqrt{150 x^{8}}

Rewriting the expression:

\sqrt{(6)(25) x^{8}}

Since \sqrt{25}=5:

5x^{4}\sqrt{6}

4) \frac{7}{\sqrt{7}}

Multiplying numerator and denominator by \sqrt{7}:

\frac{7}{\sqrt{7}} (\frac{\sqrt{7}}{\sqrt{7}})=\frac{7}{7\sqrt{7}}

Simplifying:

\sqrt{7}

5) \frac{5z}{\sqrt{25 z^{3}}}

Rewriting the expression:

\frac{5z}{5z \sqrt{z}}

Simplifying:

\frac{1}{\sqrt{z}}

Since we do not want the square root in the denominator, we can multiply numerator and denominator by \sqrt{z}:

\frac{1}{\sqrt{z}}(\frac{\sqrt{z}}{\sqrt{z}})

Finally:

\frac{\sqrt{z}}{z}
