A, B, C, or D???? Please help! Thank you!

Answer:

A is the Answer.

Step-by-step explanation:

You multiply x with 2x ( Gives you 2x^2 ) then -1 with 2x ( Gives you -2x ) then -8 with x ( Gives you -8x ) then -1 with-8 ( Gives you +8 ), finally you add the two x's ( not x^2 ). Your fibal answer will be 2x^2 - 10x +8.

Hope this helps.

Answer:

he earned 135 dolars

Step-by-step explanation:

Answer:

$135

Step-by-step explanation:

first you want to find out how much he makes for 1 hour

36/8=4.5

then you multiply 4.5 by 30 because he makes $4.5 an hour and you want to find out how much money he makes when working 30 hours

Answer:

The other endpoint is  (9, −6)

Step-by-step explanation:

(x1,y1)=(3,2) and M=(6,−2)

x1+x22=x     and     y1+y22=y

3+x22=6     and     2+y22=−2     ←×2

3+x2=12     and     2+y2=−4

x2=9              and     y2=−6

The coordinates of the other endpoint of the line segment are [tex]Y(x,y) = (-10, 11)[/tex].

Vectorially speaking, the midpoint of a line segment is determined by the following expression:

[tex]M(x,y) = \frac{1}{2}\cdot X(x,y) + \frac{1}{2}\cdot Y(x,y)[/tex] (1)

Where:

If we know that [tex]M(x,y) = (-3, 2)[/tex] and [tex]X(x,y) = (4, -7)[/tex], then the coordinates of the other endpoint is:

[tex]\frac{1}{2}\cdot Y(x,y) = M(x,y) -\frac{1}{2}\cdot X(x,y)[/tex]

[tex]Y(x,y) = 2\cdot M(x,y) -X(x,y)[/tex]

[tex]Y(x,y) = 2\cdot (-3,2)-(4,-7)[/tex]

[tex]Y(x,y) = (-6, 4) - (4, -7)[/tex]

[tex]Y(x,y) = (-10, 11)[/tex]

The coordinates of the other endpoint of the line segment are [tex]Y(x,y) = (-10, 11)[/tex].

Answer:

(-1,-6)

Step-by-step explanation:

Because it is reflecting across the x-axis, the x value remains the same but the y value moves down the axis the same distance it was, meaning that the y part of the coordinate becomes the opposite.

For example, if (1,2) was reflected across the x-axis, it becomes (1,-2).

Answer:

∠L = 50°

Step-by-step explanation:

∠R = 109°

∠U is supplementary to ∠R

This means ∠R + ∠U = 180°

109° + ∠U = 180°

Subtract ∠R from 180° to get ∠U

∠U = 81°

A triangle's angles must add up to 180, so if we take ∠U + ∠E, we figure out what 2 of the 3 angles add up to, we can then subtract this sum from 180 to figure out ∠L

81° (This is ∠U) + 49° (This is ∠E) = 130°

180° (Sum of all of a triangle's angles) - 130° (Sum of ∠U and ∠E) = 50° (∠L)

Answer:

Step-by-step explanation:

see attached image.

add all internal angles and equal to 180

∠U + ∠L + ∠E = 180

∠U = 180 - 109

     = 71

plug in values from equation:

∠U + ∠L + ∠E = 180

71 + ∠L + 49 = 180

∠L = 180 - 49 - 71

∠L = 60

The correct option that should come next at the end of this row of letters is OOXX.

A sequence can be defined as an arrangement of letters or numbers in a particular manner.

If you look at the given sequence it can be seen as the set of 5 letters where X is starting the set while O is ending the series. Also, the number of X will tend to increase in the next set as well while the number of O will be reduced. Therefore, the series can be seen as,

XOOOO  XXOOO  XXXOO  XXXXO

Thus, the correct option that should come next at the end of this row of letters is OOXX.

Answer:

If they are asking amount it is $4800.893013; $4800 (nearest dollar)

If they are asking the amount for interest is $900.8930129; $900 (nearest dollar)

Step-by-step explanation:

Compound interest Formula:

Amount = principle( 1+ rate/100)^n

Information from the question.

-So how you put it is the principle is $3900; the rate is 2.1%; the n is 10.

How to apply it?

- Just substitute in the values;

Amount=3900(1+2.1/100)^10

=4800.893013

~4800 ( nearest dollar)

》That is for amount.

Interest=4800.893013-3900

=900.893013

~900 ( nearest dollar)

2 quartz of the blue paint for every 10 quartz of yellow paint

Step-by-step explanation:

The graph shows the possible different amount of yellow paint and blue paint, in quartz, that can be mixed to obtain a shade of green paint.

On the graph, at the point with the coordinates pair of (2, 10), it means for we would require 2 quartz of blue paints to be mixed with every 10 quartz of yellow paint in order to get the shade of the green paint that we are looking for.

Answer:

$1469

Step-by-step explanation:

diameter of deck = 12 m

diameter = 2*radius

thus

12 m = 2*radius

radius = 12m / 2 = 6 m

area of circle is given by [tex]\pi r^{2}[/tex]

where r is the radius

thus, area of given deck with radius = 12 m

[tex]\pi r^{2} = 3.14*12^{2} \\=> 3.14*144 = 452.16[/tex]

Thus, area of given deck is 452.16 meter square

given

The cost of the wood stain is $3.25 per square meter

cost of 1 meter square wood stain =  $3.25

since we have to find to stain the entire deck which has area 452.16 meter square , we multiply both side of equation by 452.16

cost of  452.16 meter square wood stain =  $3.25*452.16 = $1469.25

Thus,

it will cost $1469 to the nearest dollar for   Emma to stain the entire deck
