Patty says that if you add the same negative integer five times, the sign of the sum is negative and its size is five times the

size of the original integer.
For example:
(-7) + (-7) + (-7) + (-7) + (-7)
= 5 x (-7)
= - 35

Is Patty’s statement true for all integers?

What the greatest common factor of 24 and 16? And why

GalinKa [24]

Answer:

8. (Refer to explanation)

Step-by-step explanation:

Factors of 16 and 24:

16:

1 x 16

2 x 8

4 x 4

Factors of 16 are 1, 2, 4, 8 and 16

24:

1 x 24

2 x 12

3 x 8

4 x 6

Factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24.

How to find common factor?

To find the common factor, you need to list out the factors and if a factor which is the same number appears from both 16 and 24, it is known as a common factor.

Common factors of 16 and 24 are 1, 2, 4, 8. Since greatest common factor is the number which is a common factor but is the biggest number, the answer is 8.

A triangle with an area of 37 units? is dilated by a scale factor of . Find the area of

sergeinik [125]

Answer:

<u>58 units</u>

Step-by-step explanation:

I decided that one side is 37 units and another is 2 units, since that would make the area 37 units. (you can also use 74 units and 1 unit)

Then I multiplied 37 by 5/4, which equals a new length of 46.25 units, and I also multiplied 2 by 5/4, which equals a new length of 2.5 units.

Finally, I solve for the area of the triangle:

1/2(46.25 x 2.5) ≈ <u>58 units</u> (rounded to the nearest whole number)

Point B has coordinates (4,1). The x-coordinate of point A is -4. The distance between point A and point B is 10 units. What a

klasskru [66]

Given:

Point B has coordinates (4,1).

The x-coordinate of point A is -4.

The distance between point A and point B is 10 units.

To find:

The possible coordinates of point A.

Solution:

Let the y-coordinate of point A be y. Then the two points are A(-4,y) and B(4,1).

Distance formula:

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The distance between point A and point B is 10 units.

$\sqrt{(4-(-4))^2+(1-y)^2}=10$

Taking square on both sides, we get

$(8)^2+(1-y)^2=100$

$(1-y)^2=100-64$

$(1-y)^2=36$

Taking square root on both sides, we get

$(1-y)=\pm \sqrt{36}$

$-y=\pm 6-1$

$y=1\mp 6$

$y=1-6$ and $y=1+6$

$y=-5$ and $y=7$

Therefore, the possible coordinates of point A are either (-4,-5) or (-4,7).
