Answer: LAST OPTION.

Step-by-step explanation:

1. You have the following equation:

6x^{2}=54

2. Then you must solve for x, as following:

x^{2}=54/6\\x^{2}=9\\x=\sqrt{9}\\x=+/-3

Therefore, as you can see above, the answer for the exercise is the last option.

Answer:

Choice d is correct.

Step-by-step explanation:

we have given equation

6x²=54

we have to solve this equation by using square roots.

for this, divide the above equation by 6 from both sides.

after applying division the equation become

6x²/6 = 54/6

x² = 9

now applying square root on both sides.

√x² = √9

so the final equation become:

x = ± 9

x = ± 9 is the required answer.

The answer is the range. The outliner is anything that “lies outside.” Range is the highest#-lowest#. So 78-28 = 50, which is not close the numbers that occurred most often (in this case, the #s in the 30s).

Solve for x I need help on this question
AlexFokin [52]

Answer:

x\approx7.8

Step-by-step explanation:

In relation to the given angle, we are given the triangle's opposite side and hypotenuse. Therefore, we use the sine function to set up a proportion and solve for the opposite side:

sin(\theta)=\frac{opposite}{hypotenuse}

sin(23^\circ)=\frac{x}{20}

20sin(23^\circ)=x

x=20sin(23^\circ)

x\approx7.8

Therefore, the length of the opposite side is about 7.8 units

Answer:

<h2>823.7 m²</h2>

Step-by-step explanation:

If a figure A and a figure B are similar, then

\dfrac{area_A}{area_B}=k^2    (*)

<em>k</em><em> - similarity scale</em>

<em />

Calculate the similarity scale:

k=\dfrac{6}{5}

We have the surface area of the smaller prism 572 m².

Substitute to the formula (*):

\dfrac{x}{572}=\left(\dfrac{6}{5}\right)^2\\\\\dfrac{x}{572}=\dfrac{36}{25}\qquad\text{cross multiply}\\\\25x=(36)(572)\\\\25x=20,592\qquad\text{divide both sides by 25}\\\\x=823.68\approx823.7\ m^2
