1 answer:
Novosadov [1.4K]3 years ago
6 0

Answer:

Answer: Fourth option 10x^{4}\sqrt{6}+x^{3}\sqrt{30x} -10x^{4}\sqrt{3}-x^{3}\sqrt{15x}

Step-by-step explanation:

First we open the bracket and then simplify the products in the given question.

Now we start the question.

⇒2\sqrt{10x^{4}(15x^{4})}-2x\sqrt{5x^{2}(15x^{4})} +\sqrt{10x^{4}(3x^{3}) } -x\sqrt{5x^{2}(3x^{3})}

⇒2\sqrt{150x^{8} }-2x\sqrt{75x^{6} }+\sqrt{30x^{7} } -x\sqrt{15x^{5} }

⇒2x^{4}\sqrt{150}-2x^{4} \sqrt{75}+x^{3}\sqrt{30x} -x^{3}\sqrt{15x}

⇒2(x^{4})5\sqrt{6}-2(x^{4})5\sqrt{3}+x^{3}\sqrt{30x} -x^{3}\sqrt{15x}

⇒10x^{4}\sqrt{6}+x^{3}\sqrt{30x} -10x^{4}\sqrt{3}-x^{3}\sqrt{15x}

Two times the greater of two consecutive integers is 9 less than three times the lesser integer. What are the integers?
lara [203]

Answer:

11 and 12

Step-by-step explanation:

x=smaller

y=larger

2y=3x-9    x+1=y

2(x+1)=3x-9

2x+2=3x-9

11=x

                11+1=y

                    12=y

Please respond to the question below in your own words with proper explanations
ycow [4]

Answer:

t(400)=673.

It means that 673 of 9 inch tiles are required to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.

Step-by-step explanation:

Given:

The function relating number of 9 inch tiles required and area to cover is:

t(A)=\frac{144}{9.25^2}A

Now, plug in 400 for A to evaluate t(400).

t(400)=\frac{144}{9.25^2}\times 400=\frac{144\times 400}{85.5625}=\frac{57600}{85.5625}=673.19\approx6225

Therefore, Don required  673 of 9 inch tiles to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.

Is (2, 3) a solution to the inequality y &gt; 6x + 3?
Sindrei [870]

Good morning

Answer:

NO

Step-by-step explanation:

Here we just substitute x and y by their values and see if the inequality still true or not

y = 3

6x + 3 = 6(2) + 3 = 15

since 3 < 15 then the inequality y > 6x + 3 is wrong.
