Combine like terms to create an equivalent expression.

Answer:

C. His estimate is incorrect; it should be closer to 12 than 11.

Step-by-step explanation:

1. 11^2 is 121, √(140^2) is 140, and 12^2 is 144.

2. Based off these numbers 140 is closer to 144, meaning that √(140) is closer to 12 than 11.

Therefore, the correct answer is C. His estimate is incorrect; it should be closer to 12 than 11.

Answer:

the length of Brittany's triangular sign is 1/2 the length of Will's

Step-by-step explanation:

The height of Brittany's triangle (h₁) is 2 times the height of Will's triangle (h₂).

Let's assume the height of Brittany's triangle is h₁ and the height of Will's triangle is h₂.

For Brittany's triangle:

A = ¹/₂b₁h₁ = 8

For Will's triangle:

A = /₂b₂h₂ = 8

We are also given that the base of Brittany's triangle is half as long as the base of Will's triangle

b₁ = ¹/₂b₂

Now, let's find the relationship between the heights of the triangles:

From the equations above, we can see that:

h₁ = 16 / b₁

h₂ = 16 / b₂

Recall; b₁ = ¹/₂b₂

h₁ = (2 x 16) / b₂

h₂ = 16 / b₂

So, the height of Brittany's triangle (h₁) is 2 times the height of Will's triangle (h₂).

Answer:

-2(3/2x+5)>5(2x-2)+3x

The second option

Step-by-step explanation:

If you distribute the right side:

5(2x-2)+3x

10x-10+3x

You can combine 10x and 3x because they contain the same variable.

Answer:

bro its 8 inchis

Step-by-step explanation:

According to the Associative property of Addition, when 3 or more numbers are added, the result (sum) remains the same even if the numbers are grouped in a different way. Here, grouping is done with the help of brackets.

This can be expressed as, a + (b + c) = (a + b) + c.

So, according to this the answer is 4 + (1 + 11) = (4 + 1) + 11.

Answer:

21/2, decimal form would be 10.5, mixed form is 10 1/2

Step-by-step explanation:

The number which represent represents the Commutative Property of Addition will be;

⇒ 32 + 9 = 9 + 32

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expressions are,

44 + 1 = 45

44 + 1 = 45

(16 + 2) + 18 = 16 + (2 + 18)

(16 + 2) + 18 = 16 + (2 + 18)

56 + 0 = 56

56 + 0 = 56

32 + 9 = 9 + 32

Now,

We know that;

The rule of the Commutative Property of Addition is,

⇒ a + b = b + a

Hence, The correct number which represents the Commutative Property of Addition is,

⇒ 32 + 9 = 9 + 32

Answer:

2x - 30

Step-by-step explanation:

You have to subtract 3x + 18 from 5x - 12:

=> 5x - 12 - ( 3x + 18) = 5x - 12 - 3x - 18 = 5x - 3x - 12 - 18 = 2x - 30

The first step was to apply distributive properties to get rid of the parenthesis, after that the terms were arranged and the like terms combined

100/80 = 1.25 or 125%

Answer:

The sides of an equilateral triangle are same. So if one of the sides is (x-4.5), all the sides are (x-4.5).  

Let the sides are a=(x-4.5), b=(x-4.5), c=(x-4.5)

1. Perimeter(as sum) = a+b+c

                                   =  (x-4.5)+(x-4.5)+(x-4.5)

                                   = x+x+x-4.5-4.5-4.5

                                   = 3x - 13.5

2. Perimeter (as product) = 3×a    

                                    = 3×(x-4.5)

                                    = 3×x - 3×4.5

                                    = 3x - 13.5

(you can write 3×b or 3×c also as a=b=c.)

Both perimeter as sum and perimeter as product are same as adding a number three times is the same as multiplying it by 3.

Answer:

y = 4x + (-9)

Step-by-step explanation:

You can observe that the line crosses the y-axis at -9, so that is our y-intercept.

For the slope, just take the y-intercept for example, and count how many squares the line goes up before reaching 1. In this problem you can see that the line goes 4 squares up in the time it takes to go 1 square to the right, so the slope is y over x, meaning 4 over 1, or just 4.

Answer:

The answer should be y = 4x + (-9).
