Step-by-step explanation:

-11 + 3(b + 5) = 7

-11 + 3b + 15 = 7

3b + 4 = 7

3b = 3

b = 1

Answer: The answer is A. 1.

Step-by-step explanation:

-11 <u><em>+ 3(b + 5)</em></u> = 7   Start by distributing the 3.<em> </em><u><em>3xb and 3x5.</em></u>

<u><em>-11</em></u> + 3b <em><u>+ 15</u></em> = 7    Next combine all like terms.<u><em> -11 + 15.</em></u>

<u><em>4 </em></u>+ 3b = <u><em>7</em></u>             You want to get b by itself so move the 4 using subtraction.           ..................................<u><em>4-4 and 7-4</em></u>

<em><u>3b = 3</u></em>                   B is still not by itself. Now we must divide <u><em>3 by 3 and 3 by 3.</em></u>

<u><em>b = 1</em></u>

Hope this helped. I explained the best I could.

katrin2010 [14]

Answer:

16m + 2n + 4

Step-by-step explanation:

( −2n −2) + (6 + 8m) + (8m + 4n)

−2n + −2 + 6 + 8m + 8m + 4n

(8m + 8m) + ( −2n + 4n) + (−2 + 6)

16m + 2n + 4

Point Q is the center of dilation. Line segment L M is dilated to created line segment L prime M prime. The length of L Q is 4 a
koban [17]

Answer:

The length of segment QM' = 6

Step-by-step explanation:

Given:

Q is the center of dilation

Pre-image (original image) = segment LM

New image = segment L'M'

The length of LQ = 4

The length of QM = 3

The length of LL' = 4

The original image was dilated with scale factor = 2

QM' = ?

To determine segment QM', first we would draw the diagram obtained from the given information.

Find attached the diagram

When a figure is dilated, we would have similar shape in thus cars similar triangles.

Segment L'M' = scale factor × length of LM

Let LM = x

L'M' = 2x

Using similar triangles theorem, ratio of their corresponding sides are equal.

QM/LM = QM'/L'M'

3/x = QM'/2x

6x = QM' × x

Q'M' = 6

The length of segment QM' = 6

Samuel is looking at the floor plan of his house to determine how much carpet he needs to buy for his basement. Based on the flo
DerKrebs [107]

Answer:

B) First, find two areas using (4m x 10m = 40m2) and (8m x 3m = 24m2). Next, add (40m2 + 24m2 = 64m2).

Step-by-step explanation:

Samuel should is looking to find the area of his basement in order to cover it with carpet.

An area is calculated by multiplying two dimensions (so answers A and D are not it).

Best solution is to divide the area into two large rectangles then ADD them together to get the total area.

The only scenario where he could have subtracted something based on his plan is if he would have multiplied the 10m by the 12m then subtracted the area that is not part of his basement (7mx8m).  He would have achieved the same result of course, but by going a different way.
