What is 5(x-6)=2(x+3)

Mathematics

mezya [45]3 years ago

Answer:

x = 12

Step-by-step explanation:

Given

5(x - 6) = 2(x + 3) ← distribute parenthesis on both sides

5x - 30 = 2x + 6 ( subtract 2x from both sides )

3x - 30 = 6 ( add 30 to both sides )

3x = 36 ( divide both sides by 3 )

x = 12

Answer:

<h2><u>question 1</u></h2>

n^{2} - 20n -96 = 0

use product and sum method

product = -96

sum = -20

numbers needed = ( -24 , 4)

n - 24 = 0

n + 4 = 0

hence <u>n = 24 and n = -4 </u>

<u></u>

<h2><u>Question 2 </u></h2>

<u />x^{2} + 12 x = 48<u />

in the form ax^{2}  +bx +c = 0

= x^{2} +12x - 48

make use of the formula :

\frac{-b+-\sqrt{b^{2} -4ac} }{2a}

replace values to make 2 equations :

1.\frac{-12+\sqrt{12^{2} -4*1*-48} }{2*1} = 3.17

2.\frac{-12-\sqrt{12^{2} -4*1*-48} }{2*1} = -15.2

hence <u>x = 3.17 and x = -15.2</u>

<u />

<h2><u>Question 3 </u></h2>

<u />x^{2} -14x+40=0<u />

use product and sum method

product = 40

sum = -14

numbers needed = (-10 , -4)

x - 10 = 0

x - 4 = 0

hence<u> x = 10 and x = 4</u>

<u />

<h2><u>Question 4 </u></h2>

<u />5b^{2} -20b-18 = 7<u />

in the form ax^{2}  +bx +c = 0

this becomes 5b^{2} -20b-18-7

= 5b^{2} -20b-25

can simplify by 5

= b^{2} -4b-5 =0\\

use product and sum method

product = -5

sum = -4

numbers needed (-5 , 1)

b-5 = 0

b + 1 = 0

hence <u>b = 5 and b = -1</u>

I did problems like that by marking the coordinates. For example it says A was at (2.3), so you’d go over 2 and up 3. Then you’d do the same for points B and C. After that you would connect the dots with lines, and it would show that both triangles are the same size meaning that it couldn’t be a dilation, since that would make the triangle be either bigger or smaller in size. The triangles would be facing the same direction, so it couldn’t be reflected over anything or rotated. The answer would be D) translation, because the image of the triangle was translated to the right 2 and up 2 for all of the points.
