Answers

Triangle A and triangle B have a Similarity coefficient equal to 2 (32/16)

If 32 is the largest side therefore the other side is 16

If 32 is the smallest side so another side is 64

Answer : 16, 64

Answer:

16，64

Step-The side with a side length of 32 may be the long side or the short sideby-step explanation，so there are two cases：

Answers

Answer:

C.4

4x-3=2x+5

x=4

Step-by-step explanation:

The number which is "three fewer than four times a number is five more than twice the number" is 4.

Linear Equation

The equation having the highest power of its variables as 1 is known as a linear equation.

How do we find the number?

Let the required number be x.

The given condition is - "Three fewer than four times a number is five more than twice the number."

Based on the given condition we will form an equation and solve it for x to find the required number.

The resulting linear equation is,

4x-3 = 2x+5

4x-2x = 5+3

2x = 8

x = 4

Hence, the required number is 4.

Answers

Answer:

k > 24

Step-by-step explanation:

To solve an inequality you must isolate the variable. Do this by using the properties of equality, specifically the property of multiplication. To get k by itself multiply both sides by 4. This way k > 24. Then, you can check your answer by plugging in any number less than or equal to 24 and solving to see if it's true.

Answer:

k = 24

Step-by-step explanation:

k is greater than or equal to 24 and 4/4 = 1 so if k is greater than or equal to 24 than that could be 24/4 and that would equal 6. that is the answer to your question.
