Answer 1

Answer:

B

Step-by-step explanation:

First combine the x³s.

-4x³ + 8x³ = 4x³

Then, combine the x²s.

2x² + 6x² = 8x²

Now, combine the remaining values.

9 + 1 = 10

Finally put it together.

4x³ + 8x² + 10

Hope that helps and maybe earns a brainliest :)

Which expression would be easier to simplify if you used associative property to change the grouping.
A. 4+(1.2+(-0.2))
B. 85+(120+80)
C. [-40+(60)]+52
D (2+3/7)+4/7
(I'll give brainliest for the correct and most accurate answer.)

Answers

Answer:

D. (2 + 3/7) + 4/7

Step-by-step explanation:

In B and C, the numbers involved in expressions are integers.

Hence, they can be easily added or subtracted.

In D, the numbers involved in expression are fractions which are not grouped together.

They can be added but by using associative property, it becomes much more easier.

That is, grouping fractions.

Dina has several small clay pots. She wants to display them in order of height, from shortest to tallest. What will be the order of the pots?​

Answers

Answer:

1. (2.5  2. ( 8 3. (2 1/3 4.(5

Step-by-step explanation:

The correct order  from shortest to tallest will be √5 , [tex]2\frac{1}{3}[/tex] , 2.5 , √ 8.

It is given that Dina has several small clay pots arranged in a order.

We have to rearrange them in correct order from shortest to tallest.

What will be the correct order from greatest to least for fractions ; 1/2 , 2/2 , 3/2 , 4/2 , 5/2 , 6/2 ?

The correct order will be ; 6/2 , 5/2 , 4/2 , 3/2 , 2/2 , 1/2.

Expressing the given numbers/fractions in decimal form.

√ 8 = 2.82 which is the tallest,

2.5 = 2.5 is second tallest,

[tex]2\frac{1}{3}[/tex] = 2.33 which is third tallest,

√5=  2.23 which is the shortest.

Thus , the correct order from shortest to tallest will be √5 , [tex]2\frac{1}{3}[/tex] , 2.5 , √ 8.

Which linear equation represents a proportion relationship?

A) y = x + 2

B) y = 3x + 0.2

C) y = -0.3x

D) y = 3x + 4

Answers

Answer:

C

Step-by-step explanation:

C because in proportions your multiply and divide, not add or subtract. Example: 2/3=4/5 is 2x5 and 3x4 which equals to 10=12 therefore 2/3=4/5 is not proportional. If they equaled they would be proportional.

Sari applied the distributive property using the greatest common factor to determine the expression that is equivalent to 84 +40. Her work is shown below.

Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40

84 + 40 = 2 (42 + 20)

What statement best describes Sari’s error?
Sari did not use correct factors for 84 in the equation.
