Answers

Answer:

-29

Step-by-step explanation:

replace the variables with the numbers provided. m = -4 so replace the m in the equation with -4:

3 - (-4)n

same thing with the n. n=-8 so replace the n in the equation with -8:

3 - (-4)(-8)

and then all you have to do after that is solve it using PEMDAS

multiply -4 and -8 first:

3 - 32

then solve 3-32 and you end up with -29.

Can someone find the factors of this equation I’ll mark u as brainlist

Answers

Answer:

x = -4 , x = -1

Step-by-step explanation:

x² + 5x + 4 = 0

1) write 5x as a sum

x² + 4x + x + 4 = 0

2) factor out x from the expression

x ( x + 4 ) + x + 4 = 0

3) factor out x + 4 from the expression

( x + 4 )( x + 1 ) = 0

4) the product of factors equals to 0

i) x + 4 = 0

x = -4

ii) x + 1 = 0

x = -1

Answers

Answer:

Gross income= $66,300

I found this for your answer

Ok so you wanna start at the y intercept, which is -4 and make a dot there. The slope is 2/3 which is y over x. So from -4, go up 2 and over to the right 3. You could also go down 2 and to the left 3 because two negatives make a positive.

There is a spinner with 10 equal areas, numbered 1 through 10. If the spinner
is spun one time, what is the probability that the result is a multiple of 2 and a
multiple of 5?

Answers

Answer:

10%

Step-by-step explanation:

The multiples of 2 are 2,4,6,8,10, and so on

The multiples of 5 are 5, 10, 15, 20 , 25, and so on

It is evident that the only one that matches up between 1-10 is 10.

There are 10 options, and our chances are random. There is only 1 option for it to be a multiple of both 2 and 5. Therefore, the probability is 1/10, or 10%

B: 8^3 in squared

Step-by-step explanation:

2^3 = 2*2*2= 8

4^3 =4*4*4=64

Area of rectangle equals length times width.

So, 8 * 64 equals 512 and 8^3= 512

Use calculator. Also, you can just treat it as normal multiplication and choose the one with the same units. so it would be 8, but then the next thing you would need to look at is the exponent. Since 8^6 is not the same exponent as the two in the problem, it has to be the 8^3, which are the same

Find the measures of the angles in a triangle with the ratio of 2:7:9

Answers

Answer: 20, 70, 90

====================================================

Work Shown:

Let x be some positive real number.

Multiply each part of the given ratio by x to get 2x:7x:9x

So we have the three angles 2x, 7x, and 9x.

For any triangle, the three angles must add to 180

2x+7x+9x = 180

18x = 180

x = 180/18

x = 10

This leads to

2x = 2*10 = 207x = 7*10 = 709x = 9*10 = 90

The three angles of this triangle are: 20, 70, 90

This is a right triangle due to the 90 degree angle.
