Step-by-step explanation:

Given equation = a² + 2ab + b² + a + b

Let's factorise,

We know that,

[tex]{(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} [/tex]

==================================================

Explanation:

When intersecting two lines to form an X shape, the vertical angles are the ones that form opposite one another. They do not have to align vertically, meaning they don't have to be stacked on top of one another. They could be side by side.

This applies to the following angle pairs

The items in bold apply to choices B through D

Side note: Vertical angles are always congruent.

Answer:

2nd, 3rd and 4th options

Step-by-step explanation:

when two lines intersect to make an X , angles on opposite sides of the X are called vertical angles. These angles are congruent.

from the listed angles the following are vertical angles.

∠ 5 and ∠ 7

∠ 3 and ∠ 1

∠ 4 and ∠ 2

Other vertical angles in the diagrm include

∠ 6 and ∠ 8

∠ 9 and ∠ 11

∠ 10 and ∠ 12

∠ 13 and ∠ 15

∠ 14 and ∠ 16

Answer:

50 m

Step-by-step explanation:

We find the perimeter by adding all the sides of our figure.

The initial figure has perimeter :

P = 2 + 5 + 1 + 3 + 3 + 1 + 5

P = 20 m

The dilated figure with the scale factor of 2.5 has perimeter:

P = (2 + 5 + 1 + 3 + 3 + 1 + 5 ) · 2.5

P = 20 * 2.5 = 50 m

6 = 10

Step-by-step explanation:

To help with future questions, take whatever is for the x and plug it into the equation

Answer:

22,19,13,10

Step-by-step explanation:

First, Replace the x in the equation with parenthesis (), then inside of the () put the x value in the table so it would look like: y=28-3(2). Then solve by multiplying 2 by 3 so you have y=28-6. Then just subtract 6 from 28 to get 22. Rinse and repeat for the rest of the values. Your first value will be 22, second 19, third 13, and lastly 10. Hope this helps!

Answer:

72 points

If you can get 8 each time that would be the same as doing 8+8+8...

The problem also states that if he hits it 8 times in a row you add 8 more points.

64+8=72

There are 72 points Brady receive if he hits the target 8 times in a row.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Alex is playing a game where he gets 8 points 8 every time his ball hits the target.

And, He gets an extra 8 points every time his ball hits the target 8 times in a row.

Hence, Number of points Brady receive if he hits the target 8 times in a row is,

⇒ 8 x 8 + 8

⇒ 64 + 8

⇒ 72

Thus, There are 72 points Brady receive if he hits the target 8 times in a row.

Answer: 13%

Step-by-step explanation:

Step 1:

5000

10% of 5000=500

5% of 5000=250

25%=500+500+250= 1250 rupees

so...

5000-1250= 3750 INR, which is the original price, BEFORE THE 25% WAS ADDED

but..

They only want a 10% discount of the price which is 25% above the cost (5000). So essentially we want to find  15%, because 25%-10%=15%

so if...

10%=500

5%=250

15%=750 INR

this means the price with the 10% discount off 25%= 4250 INR (5000-750)

now we need to find the percentage change. For this we need to subtract the price with the 15% discount with the price BEFORE THE 25% was added

e.g 4250-3750= 500INR

Then.. divide this price with the original price before the 25% was added

e.g 500/3750= 2/15=0.13

So...

Convert 0.13 into a percentage=13%

The PERCENTAGE PROFIT of the owner is 13%

Answer:

C. [tex](4+ (-6.5)) +11.5[/tex]

Step-by-step explanation:

Just exchange:

11.5 + (4 + ( - 6.5  ) )

⇒  (4+ (-6.5)) +11.5

After applying the property the expression would be  (4+ (-6.5)) +11.5.

Changes to the order of the addends have no effect on the sum, according to the associative feature of addition.

For example, ( 2 + 3 ) + 4 = 2 + ( 3 + 4 ) or (2 + 3) + 4

Given:

11.5+ (4+ (-6.5))

In Above case we can use the  Associative property over addition.

For this we just need to exchange the position of number along with their signs.

So, 11.5+ (4+ (-6.5))

=  (4+ (-6.5)) +11.5

Hence, after applying the property the expression would be  (4+ (-6.5)) +11.5.

Answer:

  (a)  ∠1 and ∠5

Step-by-step explanation:

Complementary angles are angles whose measures total 90°. The angles do not have to be adjacent.

__

In this geometry, we can see that angles 1 and 2 are complementary, as are angles 4 and 5, since their respective sums are right angles. Angles 2 and 5 are vertical angles, so have the same measure.

  ∠1 + ∠2 = 90° . . . . . . adjacent angles that total a right angle

  ∠1 +∠5 = 90° . . . . . substitute ∠5 for ∠2, since measures are equal

This means angles 1 and 5 are complementary.

Step-by-step explanation:

The following solution is arrived at by using the formula for the area of a regular octagon in relation to its Apotem which in this case is 18. Hence the area of the Octagon given is 1,446.

An apothem is defined as a line from the center of a regular polygon at right angles to any of its sides.

The calculation for this shape using only it's apothem has some curved bends. In order to derive the area, we have to divide the octagon into triangles.

When we find the area of the triangles we can then multiply by the total number to get the area of the Octagon.

Hence we can say that the area of the Octagon (A) = (1/2b*h)n

Where b = base

           h = height

           n = number of triangles.

Recall that the total angle in a circle is 360°, hence given that all the triangles are equal, we must divide 360° by  8 triangles to get the angle in the vertex of each triangle.

Thus, 360°/8 = 45°

So we have The angle of our triangle which is opposite the base.

Recall that the triangle is split in two so that each of the triangles are right-angled triangle,

Hence, the angle opposite the base for each right angle triangle is given as:

45°/2 = 22.5°

So to get the length of the opposite side (x), we use the law of tangents:

Which means:

x = 18 Tan 22.5°

= 18 * 0.55785173935

≈ 10.04

So if x is ≈ 10.04, then area of that triangle is

= 1/2 * 10.04 * 18 (that is 1/2bh)

= 90.3792

From the above, we can state that the Area of the triangle with the Apothem is

= 90.3792 * 2

= 180.74

Recall our formula for finding the area of the octagon:

A = (1/2bh)n

A = (108.74) *8

A = 1,445.95

≈ 1,446
