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}

Answer:

−(7p+6)−2(−1−2p) = - 3p - 4

Step-by-step explanation:

−(7p+6)−2(−1−2p) = -7p - 6 + 2 + 4p

                            = (-7p + 4p) + (2 - 6)

                            = -(7p - 4p) - (6 - 2)

                           = - 3p - 4

Solve the inequality 2x>30+5/4x
insens350 [35]

Answer:

Step-by-step explanation:

2x > 30+\frac{5}{4x} \\2x-\frac{5}{4x} > 30\\\frac{8x^2-5}{4x} > 30\\case~1\\if~x > 0\\8x^2-5 > 120x\\8x^2-120x > 5\\x^2-15x > \frac{5}{8} \\adding~(-\frac{15}{2} )^2~to~both~sides\\(x-\frac{15}{2} )^2 > \frac{5}{8}+\frac{225}{4} \\(x-\frac{15}{2} )^2 > \frac{455}{8} \\x-\frac{15}{2} < -\sqrt{\frac{455}{8} }  \\x < \frac{15}{2}-\sqrt{\frac{455}{8} } \\or~x < 0\\rejected~as~x > 0

x-\frac{15}{2} > \sqrt{\frac{455}{8} } \\x > \frac{15}{2} +\sqrt{\frac{455}{8} }

case~2

if~x < 0\\8x^2-5 < 120x\\8x^2-120x < 5\\x^2-15x < \frac{5}{8} \\adding~(-\frac{15}{2} )^2\\(x-\frac{15}{2} )^2 < \frac{5}{8} +(-\frac{15}{2} )^2\\|x-\frac{15}{2} | < \frac{5+450}{8} \\-\sqrt{\frac{455}{8} } < x-\frac{15}{2} < \sqrt{\frac{455}{8} } \\\frac{15}{2} -\sqrt{\frac{455}{8} } < x < \frac{15}{2} +\sqrt{\frac{455}{8} } \\but~x < 0\\7.5-\sqrt{\frac{455}{8} } < x < 0

if there are two containers of sugar solution, the first is 4% concentration and second is 8% concentration. how much of each sh
Elina [12.6K]

Answer:

<u>30 gallons solution 4% and 10 gallons solution 8%</u>

Step-by-step explanation:

<h3>x•4%+y•8%=40•5% </h3>

<em><u>4x+8y=40•5 and x+y=40</u></em>

x=40-y

4(40-y)+8y=200

160-4y+8y=200

4y=200-160

4y=40 => y=10 (gallons solution 8%)

=> x=40-10=30 (gallons solution 4%)

30 gallons solution 4% and 10 gallons solution 8%

16.8 - (-23.72)+(-31.3) = x
KatRina [158]

Let's solve  your equation step-by-step

16.8-(-23.72)-31.3=x

Step 1:simplify both sides of the equation

16.8-(-23.72)-31.3=x

16.8+23.72+-31.3=x

(16.8+23.72+-31.3)=x (combine like terms)

9.22=x

9.22=x

Step 2: flip the equation

Answer: x=9.22
