Answer:

  (b) 3x^2 +6x+4

Step-by-step explanation:

  (6x+7+x^2)+(2x^2-3)

  = (1 +2)x^2 +(6)x +(7 -3) . . . . combine like terms

  = 3x^2 +6x +4

Answer:

3x ² + 6x + 4

Step-by-step explanation:

( 6x + 7 + x² ) + ( 2x² -3 )

  • Remove unnecessary parantheses

6x + 7 + x² + ( 2 x² - 3 )

6 x + 7 + x² + 2x ² - 3

  • subtract the numbers

6 x + 7 - 4 + x² + 2x²

  • collect like terms

6x + 4 + 3x²

  • use the commutative property to reorder the terms

3x ² + 6x + 4

Licemer1 [7]
I think the answer is 12 because the greatest common factor of 24 and 36 is 12.

Hope this helped☺☺

(That means each goody bag will have 2 pencils and 3 erasers)

<h3>Answer: \large \boldsymbol {\sf 2\sqrt{13} \approx7,2}</h3>

Step-by-step explanation:

  • Find the distance between points A and B by the formula:

  • \large  \boldsymbol {\sf D=\sqrt{(x_1-x_2)^2+(y_1+y_2)^2} }

  • \large \boldsymbol{}  \sf D=\sqrt{(2-12)^2+(-10-5)^2} =\sqrt{100+225} =\boldsymbol {\sqrt{325}=5\sqrt{13}  }  

  • By the condition we are told to find 2/5 the distance between points A and B

  • \sf \large \boldsymbol {} \dfrac{2}{5} \cdot D=5\sqrt{13}  \cdot \dfrac{2}{5} =\boxed{\sf 2\sqrt{13}}

  • We can also find the distance between them through the  Pythagorean theorem we will complete a right triangle
  • AB²=AC²+BC²
  • AB=√AC²+BC²
  • Where AC=10  ; BC=15  
  • AB=\boldsymbol {\sf \sqrt{15^2+10^2}=\sqrt{325}=5\sqrt{13}   }
  • Then 2/5* AB=2\sqrt{13}

Akimi4 [234]

Answer:

15,159

Step-by-step explanation:

No, of cinema screen in the country in 2016 = 46,500

percentage of digital​ 3-D screens = 32.6​%

No. of  digital​ 3-D screens in numbers = total No, of cinema screen in the country * percentage of digital​ 3-D screens

No. of  digital​ 3-D screens in numbers = 46,500 * 32.6​%

 = 46,500 * 32.6​/100 = 15,159.

No. of  digital​ 3-D screens in 2016 is 15,159.
