Renn has a 36-cm scarf. He decides to cut off part of thescarf so it is now only 19 cm.
How many centimeters did Renn cut off of his scarf?
cm

Answers

Answer 1

Answer:

17 cm

Step-by-step explanation:

Since initially the scaff was 36 cm but Renn cuts x cm so that the remaining portion is 19 cm, we can express it mathematically as shown

36-x=19

To find the value of x

36-19=x

X=17 cm

The following examples illustrate the commutative property of addition. 7 + 8 + 3 = 7 + 3 + 8 4.6 + 11.4 = 11.4 + 4.6 Study the examples, then choose the statement that best describes the property. a + b = a – b a + (b + c) = (a + b) + c
a + b = a + c
a + b = b + a

Answers

Answer:

a + b = b + a

Step-by-step explanation:

The commutative property of addition allows us to "switch" values around an addition sign.

The first choice is a+b = a-b. The operation is changed; the problem is not just flipped around. This is not the commutative property.

The second choice is a+(b+c) = (a+b)+c. In this problem, the parentheses are switched; this is an example of the associative property, not the commutative property.

The third choice is a+b = a+c. The values that are added are changed, not flipped; this is not the commutative property.

The last choice is a+b = b+a. In this equation, the values are flipped around the addition symbol; this is the commutative property.

Option D is our correct answer.

a + b = b + a.

Given,

commutative property of addition.

7 + 8 + 3 = 7 + 3 + 8

4.6 + 11.4 = 11.4 + 4.6

We have to choose from the option that describes the commutativeproperty of addition.

- a + b = a – b

- a + (b + c) = (a + b) + c

- a + b = a + c

- a + b = b + a

What is the commutative property of addition?

It states that if we change the order of the values with the addition the answer remains the same.

4 + 2 = 2 + 4.

We have,

a + b = a – b

Here the order is the same on both sides but the answer is not the same on both sides.

a + (b + c) = (a + b) + c

This is a property of associative.

a + b = a + c

Here the values are not the same on both sides.

a + b = b + a

The values are the same on both sides and the order is changed.

This is the commutative property of addition.

Thus a + b = b + a is our correct answer.

PLZ HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! If f(x) = 3x2 - 2x + 5, find f(-2).

Answers

Hello from MrBillDoesMath!

Answer:

Discussion:

f(x) = 3x2 - 2x + 5

Substitute x = -2 in f(x) above to get

f(-2) =

3 (-2)^2 - 2(-2) + 5 = => (-2)^2 = (-2) * (-2) = +4, -2(-2) + + 4

3*4 + 4 + 5 =

12 + 4 + 5 =

the area of the base of a square notepad is 2.25 square inches. what is the length of one side of the base of the notepad

Answers

The area of a square is the length of one side squared, so to find the length of a side, find the square root of the area. The square root of this notepad's area (2.25) is 1.5 inches, so that is the length of one side of the notepad.

A triangle can be formed with side lengths 2 in, 3 in, and 6 in.

Answers

False in a triangle 2 sides are the same and one is different.

We have to determine

A triangle can be formed with side lengths 2 in, 3 in, and 6 in.

According to the question

A triangle can be formed with side lengths 2 in, 3 in, and 6 in.

For three line segments to be able to form any triangle you must be able to take any two sides, add their length and this sum be greater than the remaining side.

The sum of two smaller sides is

$= 2+3 \n\n= 5$

So, 5 inches < 6 inches

Hence, False in a triangle 2 sides are the same and one is different.

The two small sides of the triangle should add up and equal to the largest side.
2 + 3 = 5, 5 is smaller than 6, so the answer is NO because, at least there is a side that has the number close to each other, but if it is too far away, then 2 in can't reach to 6 in. to formed a triangle
So the answer is No
Hoped this will helped you!
