NNADVOKAT [17]

Answer:

x=14

Step-by-step explanation:

6(-6+x)=76-2x

Distribute

-36 +6x = 76 -2x

Add 2x to each side

-36+6x+2x = 76-2x+2x

-36 +8x = 76

Add 36 to each side

-36+36 +8x = 76+36

8x = 112

Divide by 8

8x/8 = 112/8

x=14

Subtract (7x^5-12x^2y+33y^2) from (5x^5-5x^2y+9y^2) simplify your results:

hoa [83]

Answer:

- 2 $x^{5}$ + 7x²y - 24y²

Step-by-step explanation:

( 5 $x^{5}$ - 5x²y + 9y² ) - ( 7 $x^{5}$ - 12x²y + 33y² ) =

5 $x^{5}$ - 5x²y + 9y² - 7 $x^{5}$ + 12x²y - 33y² =

( 5 $x^{5}$ - 7 $x^{5}$ ) + ( - 5x²y + 12x²y ) + ( 9y² - 33y² ) =

- 2  $x^{5}$  + 7x²y - 24y²

Which choices are equivalent to the expression below? Check all that apply. 5 square root 3

blsea [12.9K]

Option A: $\sqrt{75}$

Option C: $\sqrt{15} \cdot \sqrt{5}$

Option F: $\sqrt{25} \cdot \sqrt{3}$

Solution:

Given expression is $5 \sqrt{3}$ .

Option A: $\sqrt{75}$

$\sqrt{75}=\sqrt{25\times3}$

$=\sqrt{5^2\times3}$

$=5\sqrt{3}$

Hence $\sqrt{75}$ is equivalent expression of $5 \sqrt{3}$ .

Option B: $\sqrt{45}$

$\sqrt{45}=\sqrt{9\times5}$

$=\sqrt{3^2\times5}$

$=3\sqrt{5}$

Hence $\sqrt{45}$ is not equivalent expression of $5 \sqrt{3}$ .

Option C: $\sqrt{15} \cdot \sqrt{5}$

$\sqrt{15} \cdot \sqrt{5}=\sqrt{15\times5}$

$=\sqrt{75}$

$=5\sqrt{3}$ (proved in option A)

Hence $\sqrt{15} \cdot \sqrt{5}$ is equivalent expression of $5 \sqrt{3}$ .

Option D: $\sqrt{3} \cdot \sqrt{5}$

$\sqrt{3} \cdot \sqrt{5}=\sqrt{3\times5}$

$=\sqrt{15}$

Hence $\sqrt{3} \cdot \sqrt{5}$ is not equivalent expression of $5 \sqrt{3}$ .

Option E: 75

75 is a whole number.

Hence 75 is not equivalent expression of $5 \sqrt{3}$ .

Option F: $\sqrt{25} \cdot \sqrt{3}$

$\sqrt{25} \cdot \sqrt{3}=\sqrt{25\times3}$

$=\sqrt{75}$

$=5\sqrt{3}$ (proved in option A)

Hence $\sqrt{25} \cdot \sqrt{3}$ is equivalent expression of $5 \sqrt{3}$ .

Therefore, $\sqrt{75},\ \ \sqrt{15} \cdot \sqrt{5}, \ \ \sqrt{25} \cdot \sqrt{3}$ are all equivalent expressions of $5 \sqrt{3}$ .
