  7 + 2(x - 3) + 5x

= 7 +  2x - 6  + 5x     <em>distributed 2 into x - 3</em>

= 7 - 6  +  2x + 5x     <em>grouped like terms together</em>

=    1     +     7x

You didn't provide an image of the steps but hopefully you can figure it out based on the information I provided.

Which units should she use to report the distance from the earth to the moon?
Anvisha [2.4K]
Well,

The distance from the earth to the moon, FYI, is over 200,000 miles.  That is a LONG distance.  We are trying to find a reasonable unit of measurement.

What do we mean by "reasonable?"  We mean that that unit should be able to express the distance as a number that is not huge or tiny.  In other words, we want it to be as close as possible to 1.

mm, or millimeters, is a tiny unit.  It is not reasonable.

cm, or centimeters, is also a tiny unit.  It also is not reasonable.

m, or meters, is also a relatively small unit.  It also is not reasonable.

km, or kilometers, is the largest of the four.  In km, the distance from the earth to the moon is about 363,000 km.  That's not too bad.

However, if these weren't the only options, I would choose Mm, or megameters, which would put the distance at 363 Mm.

The correct option is D.

balandron [24]
1. You have that the rule for a number pattern is add 4 and the <span>first term is 7.

 2. Let's call "n" to the number in the line where each student is. Then, you can express this as below:

 4n+7

 3. So, you have:

 Student N°1=4(1)+7=11
</span> Student N°2=4(2)+7=15
 Student N°3=4(3)+7=19
 Student N°4=4(4)+7=23
 Student N°5=4(5)+7=27
 Student N°6=4(6)+7=31
 Student N°7=4(7)+7=35
 Student N°8=4(8)+7=39
<span>
 What number should Jenna say?

 The answer is: 39</span>

They have a rectangle ABCD as shown below, where AB = 24cm BC = 10cm and AE = 13cm
alex41 [277]

Answer:

A. Area of ABCD = 240 cm^{2}

B. 60 cm

C. 36 cm

D. 50 cm

Step-by-step explanation:

Given: AB = 24cm BC = 10cm and AE = 13cm.

A.  Since a rectangle is a 2 dimensional figure, it has no volume but area.

So that,

the area of the rectangle ABCD = length x width

                                                     = 24 x 10

                                                     = 240 cm^{2}

B. To calculate the circumference of the BCD triangle, apply the Pythagoras theorem to determine BD.

BD^{2} = BC^{2} + DC^{2}

       = 10^{2} + 24^{2}

       = 676

BD = \sqrt{676}

     = 26

BD = 26 cm

so that,

the circumference of BCD = 10 + 24 + 26

                                         =   60 cm

C. To calculate the circumference of the BEC triangle,

AC = 26 cm, AE = 13 cm

CE = 26 - 13

     = 13 cm

CE = 13 cm

The circumference of the BEC triangle = 13 + 13 + 10

                                                                 = 36 cm

D. The circumference of the DEC triangle = 13 + 13 + 24

                                                                 = 50 cm
