Answer:

(-3a+4b) (2x+2y)

Step-by-step explanation:

Expand.

4(x+y)(3a-b)+6(x+y)(2b-3a) = 4(3ax+3ay-bx-by) + 6(2bx+2by-3ax-3ay)

4(3ax+3ay-bx-by) + 6(2bx+2by-3ax-3ay)  = 12ax+12ay-4bx-4by+12bx+12by-18ax-18ay

Calculate like terms.

12ax+12ay-4bx-4by+12bx+12by-18ax-18ay = -6ax-6ay+8bx+8by

Factorise.

-6ax-6ay+8bx+8by = -3a(2x+2y) + 4b(2x+2y)

Factorise further.

-3a(2x+2y)+4b(2x+2y) = (-3a+4b) (2x+2y)

Answer:

x = 17

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

6x - 15 + 4x - 7 + 2x - 2 = 180, that is

12x - 24 = 180 ( add 24 to both sides )

12x = 204 ( divide both sides by 12 )

x = 17

Step-by-step explanation:

Answer:

(y - 25) = - 0.25(x - 20)

Step-by-step explanation:

Given that :

Height of candle after burning for 20 minutes = 25 cm

Height after burning for 1 hr (60 minutes) = 10 cm

Height (y) in cm of candle x minutes after being lit:

Using the equation :

(y - y1) = m(x - x1)

m = (change in y / change in x)

Change in height within 60 minutes :

Height at 20 minutes = 25cm

Height after an hour = 10

Change in height per hour = (25 - 10) = 15cm

Hence, m = change in height per minute

15cm / 60 = 0.25cm ( - 0.25) (decrease in height)

y1 = 25 ; x1 = 20

(y - y1) = m(x - x1)

(y - 25) = - 0.25(x - 20)

Hey there !

Solution:

Let the number be x

=> x + 2x² = 10

=> 2x² + x - 10 = 0

Factorising the quadratic equation we get,

=> 2x² + 5x - 4x - 10 = 0

=> x ( 2x + 5 ) -2 ( 2x + 5 ) = 0

=> ( x - 2 ) ( 2x + 5 ) = 0

=> x = 2, -5/2

Since x is a whole number, -5 / 2 wont be applicable.

Hence x = 2.

Hence the number is 2.

Hope my answer helped !

Answer:

175

Step-by-step explanation:

90 + 85 = 175

180 - 175 = 5

180 - 5 = 175 = x

Answer: 3mn^2.

Step-by-step explanation: GCF stands for Greatest Common Factor, as you know. The greatest common factor of 75 and 27 is 3. For the rest, we just use the smallest values. Thus, the answer is 3mn^2.

Answer:

10(g*h)

Step-by-step explanation:

the * is supposed to mean times/multiply

since it is an expression you do not put y= or f(x)= or anything like that

Answer:

10(g*h)

Step-by-step explanation:

"Product" means multiply so you would want to multiply g and h together. You put it in parenthesis because you want to multiply the solution you get from multiplying g and h by 10. To show this, you can simply just put the 10 in front of  the parenthesis as that implies multiplication.

Answer: the answer is really -8 (A)

Step-by-step explanation:

y=3/4x-2

Answer:

y=3/4x-2

Step-by-step explanation:

slope-intercept formual: y = mx + b

m (the slope) = (y2-y1) / (x2-x1) so right here we insert (4-1) / (8-4) = 3/4  

b =w here the line touches the y-asix = -2

now insert those numbers in the formual: y = (3/4)x + (-2)

final answer: y=3/4x-2

Answer:

Answer: C. (1,1)

Step-by-step explanation:

Midpoint

Given a segment defined by points (x1,y1) and (x2,y2), the midpoint (xm,ym) is calculated as follows:

[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]

[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]

The endpoints are (-2,-4) and (4,6).

Calculating the midpoint:

[tex]\displaystyle x_m=\frac{-2+4}{2}=\frac{2}{2}=1[/tex]

[tex]\displaystyle y_m=\frac{-4+6}{2}=\frac{2}{2}=1[/tex]

The midpoint is (1,1).

Answer:

$65m + 125 = 1165

Step-by-step explanation:

Answer:

The value of each book is 7  

The value of each music note is 6

Step-by-step explanation:

The first equation includes the sum of 3 books and 2 music notes, so 3b + 2m = 33.

The second equation includes the sum of 1 book and 3 music notes, so b + 3m = 25.

This is the system that represents the puzzle:

3b + 2m = 33

b + 3m = 25  

Solve the second equation for b, and then substitute the equivalent expression for b in the first equation.  The value of each music note is 6.

Then, Substitute the value of m into one of the original equations to find the value of b . The value of each book is 7.

Complete question :

On average, light emitted from the Sun takes 8 minutes 19 seconds to reach Earth. Using your approximated speed of light from part (b), as well as the equation distance = rate x time, calculate the approximate distance from the Earth to the Sun in meters. Write your answer in standard form and in scientific notation.

Answer:

1.497 * 10^8km

149700000 km

Step-by-step explanation:

Given that:

Time taken = 8 minutes 19 seconds

Speed of light = 3 * 10^8 m/s

Distance from earth to sun :

Speed * time

(3 * 10^8) * ((8 * 60) + 19)

(3 * 10^8) * 499

= 1497 * 10^8 m or 1497 * 10^5 km = 1.497 * 10^8km

= 149700000000 m

= 149700000 km

= 1497
