Answer:

\boxed{ \bold{  \huge{ \boxed{ \sf{8 + 8i}}}}}

Option D is the correct option.

Step-by-step explanation:

\sf{(3 + i) + (5 + 7i)}

When there is a ( + ) in front of an expression in parentheses , there is no need to change the sign.

That means, the expression remains the same.

Just remove the unnecessary parentheses

⇒\sf{3 + i + 5 + 7i}

Collect like terms and simplify

⇒\sf{3 + 5 + i + 7i}

⇒\sf{8 + 8i}

Hope I helped!

Best regards!!

The ravens scored 13 more than three times number points that the bengals scored in their last game. If the ravens scored 40 poi
katrin2010 [14]

The score of Raven is 9 points

<em><u>Solution:</u></em>

Let the point scored by bangal be"x"

Score of Raven = 40 points

Given that,

The ravens scored 13 more than three times number points that the bangals scored in their last game

Score of raven = 13 + 3(score of bangal)

40 = 13 + 3x

Solve the above equation for x

3x = 40 - 13

3x = 27

x = 9

Thus the score of Raven is 9 points

Right or wrong ????
tangare [24]

Answer:

c   1/2

Step-by-step explanation:

You are incorrect.

We are going from ABCDEFGH to A'B'C'D'E'F'G'H'. We are going from the large octagon to the small octagon. The scale factor of a dilation is the number you multiply the original lengths to get the lengths of the dilation.

scale~factor = \dfrac{length~of~dimension~in~dilated~image}{length~of~corresponding~dimension~in~original~figure}

Look at point (6, 0) which becomes (3, 0) in the dilation.

The distance from the origin to (6, 0) is 6 units.

The distance from the origin to (3, 0) is 3 units.

scale factor = dilated/original = 3/6 = 1/2

The scale factor of the dilation is 1/2.

Also look at segment AB whose length is 4. The length of segment A'B' is 2.

scale factor = dilated/original = 2/4 = 1/2

Answer: 1/2
