Answer:

[tex]6 {d}^{2} + 5cd - 3dc + 8[/tex]

Step-by-step explanation:

b/c we can substructure 5cd and 3dc b/c it doesn't matter if the place of cd and dc change. what I mean if 5 ×3=15 and it is the same with 3×5=15 both of the product are the same but, if it is - and ÷ it wil be wrong for example 5-3=2 but 3-5= -2

which is 1/3 - 1/6 in a fraction

Answers

Answer:

Step-by-step explanation:

1/3 - 1/6

2/6 -1/6= 1/6

find common denominator

For  [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex]  the fraction will be [tex]\dfrac{1}{6}[/tex] .

Given to us,

[tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex]

To solve this, firstly we need to make the denominators the same, thus taking the LCM of both 3 and 6.

As we know the LCM of 3 and 6 is 6 itself.

So, multiplying and dividing by 2.

[tex]\dfrac{1}{3}\rightarrow \dfrac{1\times 2}{3\times 2}\rightarrow \dfrac{2}{6}[/tex]

Now,

[tex]\dfrac{2}{6}-\dfrac{1}{6} = \dfrac{1}{6}[/tex]

Hence, for  [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex]  the fraction will be [tex]\dfrac{1}{6}[/tex] .

Answers

It would be the second choice. Add by 25.

Answer:

C. The relationship between the quantities is: add 25.

Step-by-step explanation:

1x = 25y,

2x = 25 + 25 = 50y

3x = 50 + 25 = 75y

4x = 75 + 25 = 100y

Note:

As you can see, every time the number goes up on the chart, it goes up by 25 and you can find that out by just simply adding 25 to the first number and seeing if it matches up with the next, (which I did above).

(TV ) ⃗ bisects ∠STU,m∠STV=(1/4 x+8)°,
and m∠UTV=(x+2)°.Find m∠STU.

Answers

Answer:

m∠STU = 20 °

Step-by-step explanation:

Since the line bisects the angle, we have that the two bisected angles are equal

Thus, mathematically;

x + 2 = x/4 + 8

Multiply through by 4

4x + 8 = x + 32

4x-x = 32-8

3x = 24

x = 24/3

x = 8

So to find the value of the original angle, we input 8 into each of the bisected angles and add together

mathematically, that will be ;

10 + 10 = 20

Answer:

Angle B = 131 degrees

Step-by-step explanation:

We know that since there's an angle labeled 139 degrees and a straight line is 180 degrees in total, the other angle is equal to 180 - 139 = 41 degrees.

Since all triangles have 3 angles that add up to 180 degrees and we know that theres a right angle, a 41 degree angle, then angle A must equal to 180 - 41 - 90 = 49 degrees.

We know that vertical angles are congruent, therefore angle C is also equal to 49 degrees.

Angle B and angle A form a straight line, which we have defined as 180 degrees.

180 - 49 = 131 degrees.

Angle B = 131 degrees
