Please help for both questions

Mathematics
1 answer:
scoundrel [369]3 years ago
4 0

Answer:

B, A

Step-by-step explanation:

In the first equation, if an unknown number plus 17 equals 66, then what step would you take?

For example, if an unknown number plus 2 equaled 3, then you would know that number is 1, right? What steps did you take to get that? You subtracted 2 from both sides.

In this example, if x + 17 = 66, then subtracting 17 from both sides gets us x = 49.

The same applies for the second example. If x minus 54 equals 125, then you would add 54 to get x = 179.

What is the approximate circumference of a circle that has a center at (3,1) and passes through the point (3,6)?
user100 [1]

Answer:

Approximately  31.42

Step-by-step explanation:

You use the Distance Formula

d= √( x2 - x1 )^2 + ( y2 - y1 )^2

substitute

r=  √(3-3)^2 + (6-1)^2

    √0^2 + 5^2

r = √25

r = 5

Now you can use the equation for  finding the circumference

2πr

2π5

≈ 31.42

Are 3x + 2 and 3 (x + 2 ) equal
Nata [24]

Answer:

No

Step-by-step explanation:

Parenthesis means to multiply. So, to simplify the expression 3(x + 2), we need to distribute 3. In other words, we need to multiply 3 to x and to 2. Thus 3(x + 2) = 3x + 6.

Discussion Topic There are four basic operations: addition, subtraction, multiplication, and division. Do you think these four o
emmainna [20.7K]

Step-by-step explanation:

1. Yes  addition, subtraction, multiplication, and division can be performed on polynomials. like our everyday arithmetic dealings with mathematical operators, polynomials are no exception when it comes to math operators, the four   basic operations addition, subtraction, multiplication, and division can be performed on polynomials as well.

2. It can be less handy plus the operation can get messy if you do not have a good sense/understanding/hold of what you are doing things can get messy.

3. I personally know that the simplest is the addition of polynomials

4. I cant say which is difficult, but the operation that can get things messy  for me most time is the division operation
