Which expression are equivalent to 2(4f+2g)

Cloud [144]

Answer:

8f+4g

Step-by-step explanation:

You have to distribute 2 to each number in the parentheses 2 times 4 is 8 and since 4 has a variable it is 8f and 2 times 2 is 4 and since 2 has a variable it is 4g. We don't combine the two because they have different variables. So the answer is 8f+4g. Hope this helped :)

What is the answer 5x-3 =1/5x

Oxana [17]

Answer:

x = 5/8 for 5x - 3 = (1/5)x

Step-by-step explanation:

To find x, we want to isolate our 3 from our x-values. You can add three to both sides of the equation and get it to the other side and then subtract 1/5x from 5x.

(5x - 3) + 3 = ((1/5)x) + 3

5x = (1/5)x + 3

5x = (25/5)x

((25/5)x) - (1/5)x = ((1/5)x + 3) - (1/5)x

(24/5)x = 3

From here, you would want to solve for x. This would mean multiplying 3 by 5 and dividing your product by 24.

5*3 = 15

15/24 = 5/8 = x

Hope this helps!

3rd question, I’m sorry guys but I was sick that’s why I didn’t attend school and the teacher said if I didn’t submit it by 5 ho

Answer:

21. ΔUYZ Obtuse

22. ΔBCD Right or Rectangle

23. ΔADB Acute

24. ΔUXZ Acute

25. ΔUWZ Right or Rectangle

26. ΔUXY Equiangular and acute

Step-by-step explanation:

We need to classify each triangle by its angles.

Acute: They have 3 acute angles (less than 90 degrees).

Rectangle: The inner angle A is straight (90 degrees) and the other 2 angles are sharp. The sides that form the right angle are called legs (c and b), the other side hypotenuse.

Obtuse: The inner angle A is obtuse (more than 90 degrees). The other 2 angles are acute.

ΔUYZ Obtuse The inner angle Y is obtuse (more than 90°).

ΔBCD Right or Rectangle The inner angle C is straight (90°).

ΔADB Acute It has 3 acute angles (less than 90°).

ΔUXZ Acute It has 3 acute angles (less than 90°).

ΔUWZ Right or Rectangle The inner angle W is straight (90°).

ΔUXY Equiangular and acute Which means all the inner angles are equal (60°).

The table shows the results of rolling a number cube, with sides labeled 1 through 6, several times.

Natalka [10]

It looks like you are missing one value in your table. You have 6 sides of the die, however only 5 outcomes. Without this, we can't get a final answer. However, I can tell you how to solve the problem.

For the experimental probability, you need to add up all the 2's and 4's. Then, divide that number by the total amount of numbers.
