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}

<h3>Total snow fall for three days is 8.75 inches</h3>

<em><u>Solution:</u></em>

Given that,

Snow fell over the past three days

First\ day = 3\frac{2}{4}\ inches = \frac{14}{4}\ inches\\\\Second\ day = 3\frac{2}{4}\ inches = \frac{14}{4}\ inches\\\\Third\ day = 1\frac{3}{4}\ inches = \frac{7}{4}\ inches

<em><u>What was the total snowfall for the three days?</u></em>

Total snowfall = first day + second day + third day

Total\ snowfall = \frac{14}{4} + \frac{14}{4} + \frac{7}{4}\\\\Total\ snowfall = \frac{14 + 14 + 7}{4}\\\\Total\ snowfall = \frac{35}{4} \text{ or } 8.75\ inches

Thus total snow fall for three days is 8.75 inches

A parallelogram has a base of 4.5 cm and an area of 9.495 cm². Tania wrote the equation 4.5x = 9.495 to represent this situation
Artist 52 [7]

Answer:

The height of the parallelogram is 2.11 cm.

Step-by-step explanation:

Area of the parallelogram is equal to multiplication of base and height.

Given:

Parallelogram has base of 4.5 cm.

Are of the parallelogram is 9.495 cm².

Equation is 4.5x=9.495

Calculation:

(a)

Are of the parallelogram is the product of base length and height of the parallelogram.

Area of the parallelogram is expressed as follow:

A=lh          

Substitute 9.495 cm² for A and 4.5 cm for l in above equation as follows:

9.495=4.5h             …… (1)

Now relate the equation (1) and given equation. So, here x is nothing but the height of the parallelogram.

(b)

From equation (1), height of the parallelogram is calculated as follows:

9.495=4.5h

h=\frac{9.495}{4.5}

h=2.11 cm

Thus, the height of the parallelogram is 2.11 cm.

Why can't a triangle have more than one obtuse angle
vlada-n [284]
An "obtuse" angle is an angle that's bigger than 90 degrees.
So two obtuse angles would add up to more than 180 degrees.

But the three angles inside a triangle always add up to exactly 180 degrees.
So two of them can't be obtuse.
