expand the brackets (x+5)(3x-2).

Answers

Answer 1

Answer: 3x^2 +13x - 10

Step-by-step explanation:

(x+5)(3x-2) = x(3x-2) + 5(3x-2)

x(3x-2) + 5(3x-2) = 3x^2 - 2x + 15x - 10

3x^2 - 2x + 15x - 10 = 3x^2 + 13x - 10

Find all numbers whose absolute value is 5.
If there is more than one, separate them with commas.
If there are no such numbers, click on "None".

Answers

Answer:

5 , |-5|

Step-by-step explanation:

2 of the above are the absolute value of 5

The two numbers whose absolute value is 5 are 5 and -5.

Numbers whose absolute value is 5 can be both positive and negative.

The absolute value of a number is its distance from zero on the number line, so any number that is 5 units away from zero in either the positive or negative direction will have an absolute value of 5.

Here are the numbers whose absolute value is 5:

5 (positive 5, because it's 5 units to the right of zero)

-5 (negative 5, because it's 5 units to the left of zero)

Hence, 5 and -5  are the two numbers whose absolute value is 5.

Solve the given equation.
- 29 = - 13 - n
Write step by step how you solved it.

Answers

Answer:

The answer is n=16

Step-by-step explanation:

Let's solve your equation step-by-step.

−29=−13−n

Step 1: Simplify both sides of the equation.

−29=−13−n

−29=−13+−n

−29=−n−13

Step 2: Flip the equation.

−n−13=−29

Step 3: Add 13 to both sides.

−n−13+13=−29+13

−n=−16

Step 4: Divide both sides by -1.

−n/−1 =−16/−1

n=16

Answer:

Step-by-step explanation:

d) The rate of change between 2 and 3 trees is different than the rate of change between 3 and 5 trees.

Number of tree purchased                            Total Cost ($)

               1                                                                 60

               4                                                                240

               5                                                                290

For the linear function rate of change is constant.

Now, between 2 and 3 trees rate of change is given by

Now, between 3 and 5 trees rate of change is given by

This is clearly that the rate of change isn't constant. Therefore, the function is non-linear.

so,

Step-by-step explanation:

240,000 = 24 x 10^4

24 followed by 4 zeros = 24 x 104

Just make the number of zeroes be the exponent for 10

24 = 24 x 10^0

240 = 24 x 10^1

2400 = 24 x 10^2

24000 = 24 x 10^3

Answer:

3#

Step-by-step explanation:

mark as a brainlist

Answer:

8 : 24 = 1 : 3

Step-by-step explanation:

The ratio is not in lowest terms so we found an equivalent ratio by simplifying

We can simplify the ratio 8 : 24 by dividing both terms by the greatest common factor (GCF).

The GCF of 8 and 24 is 8.

Divide both terms by 8.

8 ÷ 8 = 1

24 ÷ 8 = 3

Therefore:

8 : 24 = 1 : 3

Avery and Carmen both have summer jobs. Avery gets paid $360 every 4 weeks. Carmen gets paid $480 every 6 weeks. summer break lasts a total of 12 weeks. who will earn more money during summer break?

Answers

Answer:

Avery

Step-by-step explanation:

12/4=3 so Avery will be paid 3 times

360×3= $1080

12/6=2 Carmen will be paid twice

480×2=$960

Avery earns more

360/4 = $90 a week

480/6 = $80 a week

80 x 12 = 960

90 x 12 = 1080

1080 > 960

So Avery will earn more.
