So you can only simplify like terms this means that number terms like 5 can’t be added or subtracted from 5x and the x is a separate term this is the same for x^2 and so on as these are different terms and can’t be added or subtracted to other terms, next the signs in between the brackets may change whether you add or subtract so be careful with those a negative and a positive make a negative, two positives make a positive, two negatives make a positive, always check the signs when answering so
No20) (2a+9)-(4a-9) would be 2a+9-4a+9 as the minus changes the signs this then equals -2a+18
Now you can do the harder ones

OK, I cut a cake vertically to make 2 congruent parts. a) Find the perimeter and area of the cross section formed by the cut. Write your answer as a decimal. The perimeter is __ inches and the area is __ square inches. b) Find the surface area of the cake that is not frosted before the cut. Round your answer to the nearest hundredth. The surface area is about __square inches.

Answers

Answer:

The perimeter is 36.5 inches.

The area is 59.5 square inches.

The surface area is about  153.94 square inches.

Step-by-step explanation:

From the figure it is clear that,

Radius of cake = 7 in

Diameter of cake = 14 in

Height = 4.25 in

We need cut the cake vertically along its diameter to make 2 congruent parts.

So, cross section is a rectangle of length 4.25 in and width 14 in.

Perimeter of rectangle is

[tex]Perimeter=2(length+width)[/tex]

[tex]Perimeter=2(4.25+14)[/tex]

[tex]Perimeter=2(18.25)[/tex]

[tex]Perimeter=36.5[/tex]

The perimeter is 36.5 inches.

Area of rectangle is

[tex]Area=lengt\times width[/tex]

[tex]Area=4.25\times 14[/tex]

[tex]Area=59.5[/tex]

The area is 59.5 square inches.

We need to find the surface area of the cake that is not frosted before the cut. It means the area of base.

Area of circle = [tex]\pi r^2[/tex]

where, r is radius.

Area of circular base = [tex]\pi (7)^2[/tex]

[tex]=49\pi [/tex]

[tex]=153.93804[/tex]

[tex]\approx 153.94[/tex]

Therefore, the surface area is about  153.94 square inches.

Connect arcs that are above the original line with a straightedge. Create arcs on either side of a point that is off the given line. Create a copied angle by using the first two lines as the original angle.

Answers

Answer:

A because

Step-by-step explanation:

Which the following steps is included in the construction of a perpendicular line through a point on a line? Connect arcs that are above and below the given line with a straightedge. Connect arcs that are above the original line with a straightedge. Create arcs on either side of a point that is off the given line. Create a copied angle by using the first two lines as the original angle.

so the answer is A

The step included in the construction of a perpendicular line through a point on a line is the option:

Connect arcs that are above the original line with a straightedge

The reason for the above selection is as follows:

The steps in the construction of a perpendicular line through a point on a line include

The compass needle is placed at the point through which the perpendicular line is to pass and two arcs or equal radius, r, are drawn on either side of the point crossing the line

Increase the compass width to more than the radius, r, above, place the compass needle at the intersections of the arc and the line drawn above and draw an arc either above or below the line

Repeat the above step from the other intersection of the arc on the other side of the point on the line and draw another arc that intersects the arc in the above step, above or below the line

With the straightedge, draw a line from the given point that passes through the intersection of the arcs above or below the line to complete the construction of a perpendicular line passing through a point on a line

Therefore, the included step in the construction of a perpendicular line through a point is; Connect arcs that are above the original line with a straightedge
