Answer:

(-4)(3) = -12

Step-by-step explanation:

Open brackets. -4 x 3 = -12

Since it's multiplication, number doesn't matter (whether bigger or smaller), it depends on whether it is the only sign with a negative sign or not.

Factors:

- x - = +

- x + = -

+ x + = +

(x = */ multiply)

Hope this helped :)

Answer:

[tex] \frac{12}{7} [/tex]

Step-by-step explanation:

Side length of red ∆ = 12

Side length of blue ∆ = 7

Given that the red ∆ is similar to the blue ∆, therefore the ratio of their corresponding sides = the ratio of their perimeter.

The ratio of the perimeter of red ∆ to perimeter of blue ∆ = side length of red ∆ / side length of blue ∆

[tex] = \frac{12}{7} [/tex]

The ratio (red to blue) of the perimeters of the similar triangles is 12:7

Assuming that the similar triangles are equilateral triangles, then all their sides will be equal.

Perimeter of a triangle = s1 + s2 + s3

For the red triangle;

Perimeter of the red triangle = 12 + 12 + 12

Perimeter of the red triangle = 36

For the blue triangle:

Perimeter of the blue triangle = 7 + 7 + 7

Perimeter of the blue triangle = 21

Taking the ratio of their perimeters;

Ratio of red to blue = 36:21 = 12:7

Hence the ratio (red to blue) of the perimeters of the similar triangles is 12:7

Answer:

There are two real roots

Step-by-step explanation:

From the value of the discriminant b² - 4ac

• If b² - 4ac > 0 then 2 real and distinct roots

• If b² - 4ac = 0 then 2 real and equal roots

• If b² - 4ac < 0 then 2 complex roots

Here b² - 4ac = 8 > 0 , then there are two real roots

Answer:

Step-by-step explanation:

Answer:

The correct option is;

x + y = 1000

Step-by-step explanation:

The data from the table can be presented as follows

Adults (x)            [tex]{}[/tex]                              Children (y)

500                         [tex]{}[/tex]                              500

450                         [tex]{}[/tex]                              550

400                          [tex]{}[/tex]                             600

350                         [tex]{}[/tex]                              650

Therefore, we have the rate of change of the children, y to the adults, x, which is also the slope of the graph of the data given as follows;

The slope, m = dy/dx = (650 - 500)/(350 - 500) = 150/(-150) = -1

m = -1

The function of the graph in point and slope form, using the first point, becomes;

y - 500 = -1 × (x - 500) = -x + 500

∴ y - 500 = -x + 500

y + x = 500 + 500 = 1,000

Which gives

y + x = 1,000

y + x = x + y = 1,000

Answer:

the third answer, 21%

Step-by-step explanation:

the change was 15% and the original was 70 so,

15/70

=.21

Answer:

suffer no longer ! im here for u!!!~~

the answer is JKN = 57

Step-by-step explanation:

JKN is JKL + LKN

we know that LKM = 42, and LKN is half of that because KN bisects LKM (splits into 2 equal parts)

so, LKN is half of 42

LKN = 21

to find JKL, subtract 42 from 78

JKL = 36

36 + 21 = 57

Answer:

5.5

Step-by-step explanation:

20p-4(3p-6)=8(3p-6)-16

20p-12p+24=24p-48-16

8p+24=24p-64

+64 on both sides

8p+88=24p

-8p on both sides

88=16p

/16 on both sides

Answer:

D

Step-by-step explanation:

Answer:

y=8

Step-by-step explanation:

2(1)+2y=18

2+2y=18

minus 2 from both sides

2y=16

divide by 2 from both sides

y=8

Answer:

y=8

Step-by-step explanation:

1. If x is equal to 1, 2x is just 2.

2. We can subtract the 2 we already have. 18-2=16

3. 2y=16, divide by 2 on both sides.

y=8

Answer:

r = -6

Step-by-step explanation:

Use the slope formula and solve for r.

slope = y2 -y1

            x2 -x1

Since you know all the numbers except for r, plug everything in and you get:

5  = 9 - r

        9 - 6

So then do the arithmetic, you find that 9 - r = 15. So r must = -6.
