Answer:

8, 10, 12

Step-by-step explanation:

Because they are even there is a whole number x so that (1st)2x, (2nd) 2x+2, and (3rd)2x+4 are the 3 consecutive integers.

so

If the third is 8 less than twice the 2nd then:

 3rd   = 2 (2nd) - 8

2x + 4 = 2 (2x+2) - 8

2x + 4 = 4x + 4 - 8

2x + 4 = 4x - 4         Add 4 to each side

2x + 4 + 4 = 4x - 4 + 4

2x + 8 = 4x    Subtract 2x from each side

2x - 2x + 8 = 4x - 2x

8 = 2x         Divide each side by 2

8/2 = 2x/2

8/2 = x

4 = x

No we plug into our equations to find the integers.

2x = 2(4) = 8    

2x + 2 = 2(4) + 2 =  8 + 2 = 10              

2x + 4 =  2(4) + 4 =  8 + 4 = 12

So our integers are 8, 10, 12

Subtract 45 on both sides

AngleCBD = 34

The only way to really tell is to check it with the Pythagorean Theorem.

The Pythagorean Theorem describes every right triangle, and every triangle that fits the Pythagorean Theorem has a right angle in it.  Guaranteed.  This is incredibly handy.

If this IS a right triangle, then

(one leg squared) + (the other leg squared) = (the hypotenuse squared) .  

Let's check it out:

--  One leg squared = (11 cm)²  .  That's  121 cm² .

--  The other leg squared = (√99 cm)² .  That's  99 cm²  .

--  Their sum is  (121 + 99) cm² .  That's  220 cm² .

-- The hypotenuse squared is  (15 cm)² .  That's  225 cm² .

Is  220 cm² equal to  225 cm² ?

NO !  They are not equal.  They are different !

The sum of the squares of the legs is NOT equal to the square of the hippopotamus.

==>  This triangle does NOT fit the Pythagorean Theorem.

==>  It is NOT a right triangle.

(The angle in the bottom corner is slightly bigger than 90°.  But you can't tell by looking at it.  It's so close that you can only tell by checkoing the lengths againt the Pythagorean Theorem.)

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{k = 3}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{4.5 + 1.5k = 18 - 3k}[/tex]

Move 3k to left hand side and change it's sign

Similarly, move 4.5 to right hand side and change it's sign

[tex] \longrightarrow{ \sf{1.5k + 3k = 18 - 4.5}}[/tex]

Collect like terms

[tex] \longrightarrow{ \sf{4.5k = 18 - 4.5}}[/tex]

Subtract 4.5 from 18

[tex] \longrightarrow{ \sf{4.5k = 13.5}}[/tex]

Divide both sides by 4.5

[tex] \longrightarrow{ \sf{ \frac{4.5k}{4.5} = \frac{13.5}{4.5} }}[/tex]

Calculate

[tex] \longrightarrow{ \sf{k = 3}}[/tex]

Hope I helped!

Best regards! :D

Answer:

k = 3

Step-by-step explanation:

Subtract 4.5 from both sides:

4.5 + 1.5k = 18 - 3k

-4.5            -4.5

1.5k = 13.5 -3k

Subtract -3k from both sides:

1.5k = 13.5 - 3k

+3k             +3k

4.5k = 13.5

Now simplify:

4.5k = 13.5

k = 3

Answer:

x=-11

Step-by-step explanation:

Move the constant to the right

3x=-39+6

Calculate

3x=-33

Divide both sides by 3

x=-11

Answer: you would add 6 to 10

Step-by-step explanation:

The new measurement can be obtained by the formula b = 2A/h the answer is b = 2A/h

In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

We have:

Charlie runs a screen printing company and is resetting a machine he uses to print triangular banners.

Given:

A = bh/2

Make subject as b

2A = bh

b = 2A/h

Thus, the new measurement can be obtained by the formula b = 2A/h the answer is b = 2A/h

Answer:

1. 7

2. 6

Step-by-step explanation:

An inverse additive is a number that when added to its additive inverse equals 0. So, in this case -7 +7 = 0 and -6 +6 = 0.

Step-by-step explanation:

9x² + 6 = 12x

3x² + 2 = 4x

3x² − 4x + 2 = 0

Use quadratic formula.

x = [ -b ± √(b² − 4ac) ] / 2a

x = [ -(-4) ± √((-4)² − 4(3)(2)) ] / 2(3)

x = [ 4 ± √(16 − 24) ] / 6

x = [ 4 ± √(-8) ] / 6

x = (4 ± 2i√2) / 6

x = (2 ± i√2) / 3

Answer:

1.    x = 1, y = 2.

12.  x = 1, y = -3.

Step-by-step explanation:

I won't do all these for you, just the first and the last. The method is similar  for all 12.

1.

y = x + 1

x + y = 3

Substitute y = x + 1 into the second equation:

x + y = 3 so:

x + (x + 1) = 3

2x + 1 = 3

2x + 1 -1 = 3 - 1

2x = 2

x = 1.

Now substitute x = 1 into the first equation to get the value of y:

y = x + 1

y = 1 + 1

y = 2.

12.

4x = y + 7

3x + 4y + 9 = 0

Solve for y in the first equation:

4x = y + 7                Subtract 7 from both sides of the equation:

4x - 7 = y + 7 - 7

y = 4x - 7.

Now substitute  y = 4x - 7 in the second equation:

3x + 4y + 9 = 0   so:

3x + 4(4x - 7) + 9 = 0

3x + 16x - 28 + 9 = 0

19x - 19 =  0

19x - 19 + 19 = 0 + 19

19x = 19

x = 19/19 = 1.

Now substitute x = 1 in the first equation:

4x = y + 7

4*1 = y + 7              Subtract 7 from both sides of the equation:

4 - 7 = y + 7 - 7      

-3 = y.

The total cost of the leash will be $22.90. The correct option is A.

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Kirk finds a dog leash with a price tag of $24 at a pet store. The leash is 10% off the original price. He must also pay 6% sales tax.

The cost after 10% off is:-

Cost = 24 - 24 x ( 10 / 100 )

Cost = 24 - 2.4

Cost = 21.6

Total cost after 6% sales tax = 21.6 + ( 21.6 x 0.06)

Total cost after 6% sales tax = 21.6 + 1.296 = $22.9

Therefore, the total cost of the leash will be $22.90. The correct option is A.

Area of a parallelogram=base×height

=10×4

=40cm^2

The area of the parallelogram is 40 square cm if the parallelogram has a base of 10 centimeters and a height of 4 centimeters.

In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.

It is given that:

A parallelogram has a base of 10 centimeters and a height of 4 centimeters.

As we know:

Area of a parallelogram = base×height

Area of a parallelogram = 10×4

Area of a parallelogram = 40 square cm

Thus, the area of the parallelogram is 40 square cm if the parallelogram has a base of 10 centimeters and a height of 4 centimeters.
