The CORRECT answer is:

$y=3x-5$

Step-by-step explanation:

With my work shown in the image, it clearly shows that [Choice C] is perpendicular.

<em><u>Remember</u></em> that perpendicular is when a line crosses with another line making a 90 degree angle.

Parrellel is when two lines perfectly line up with each other but without crossing

The diagram below shows the dimensions of Tessa’s garden.

Leona [35]

Answer:

Tessa's mistake was to have multiplied each dimension by two instead of multiplying by a square root of two.

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z -----> the scale factor

x ----> the area of the enlarged garden

y ----> the area of the original garden

$z^{2}=\frac{x}{y}$

we have that

If Tessa multiplies each dimension by 2, then the scale factor equals 2.

$z=2$

substitute

$2^{2}=\frac{x}{y}\\\\ 4=\frac{x}{y}\\\\x=4y$

The area of the enlarged garden will be equal 4 times the area of the original garden

If Tessa wanted to have twice as much surface, she must multiply each dimension by a square root of 2.

therefore

Tessa's mistake was to have multiplied each dimension by two instead of multiplying by a square root of two

13. Fill in this diagram so that each of the rows, columns and

Natasha2012 [34]

Answer:

D. 24

Step-by-step explanation:

Let's name the diagram

Row 1: a1, a2, a3

Row 2: b1, b2, b3

Row 3: c1, c2, c3

From the diagram,

b2 and c2 have been given

All rows, columns and diagonal must sum up to 18

If b2=6 and c2=4

a2=18-(6+4)

=18-10

a2=8

Assume a1=4

Diagonals a1+b3+c3=18

4+6+c3=18

10+c3=18

c3=18-10

Assume a3=6

Diagonals a3+b2+c1=18

6+6+c1=18

12+c1=18

c1=18-12

So b1=18-(6+4)

=18-10

b1=8

b3=18-(6+8)

=18-14

b3=4

Input all the numbers into the boxes

We have,

4 8 6

8 6 4

6 4 8

Corner numbers are a1,a3,c1,c3

=4,6,6,8

Sum of all the corner numbers=4+6+6+8

=24

Why does a conjugate pair make a difference of 2 squares?

allsm [11]

Answer:

where one perfect square is subtracted from another, is called a difference of two squares. It arises when (a − b) and (a + b) are multiplied together. This is one example of what is called a special product.

Step-by-step explanation:

Every difference of squares problem can be factored as follows: a2 – b2 = (a + b)(a – b) or (a – b)(a + b). So, all you need to do to factor these types of problems is to determine what numbers squares will produce the desired results. Step 3: Determine if the remaining factors can be factored any further.
