The correct option is (A) Yes they are similar.

Explanation:
One quadrilateral (the red one) is the scaled version of the other quadrilateral (the blue one).

All you need is to reflect and dilate the blue one to make the red one.

Hence they are similar to each other. The question is asking about similarity; therefore the correct option is (A) Yes they are similar.

Answer:

x=4

Step-by-step explanation:

-7x=-28

-7 -7

x=4

Divide both sides by -7. A negative divided by a negative will give you a positive. So the answer would be x=4.

Answer:

x=4

you divide both sides by -7 to get the x by itself. -28 divided by -7 is 4.

HELP!!!!!In a group of 15 children, 5 said they are an only child, 3 said they have 1 sibling only, 4 said they have exactly 2 siblings, and 3 said they have exactly 3 siblings.

What is the average number of siblings for this group? Enter your answer as a decimal, rounded to the nearest tenth,
_______

Answers

The average number of siblings for the group is 1.3.

We must compute the total number of siblings and divide it by the total number of children in the group to determine the average number of siblings for the group.

There are a total of: siblings in the bunch.

3 + 8 + 9 = 20 (1 sibling times 3 children) + (2 siblings times 4 children) + (3 siblings times 3 children)

The total number of kids in the group is: 5 + 3 + 4 + 3 = 15

As a result, the group as a whole has an average of:

20/15 = 1.33 (rounded to the nearest tenth) (rounded to the nearest tenth)

So, the group as a whole has 1.3 siblings on average.

4(4x - 2) = x + 4
asnwerplsssssssss

Answers

Answer:

4(4x - 2) = x + 4

16x - 8 = x + 4

15x = 12

x = 12/15 = 4/5

Answer:

x = 0.8

Step-by-step explanation:

4(4x - 2) = x + 4

16x - 8 = x + 4

16x - x = 4 + 8

15x = 12

x = 0.8

What is the solution to x^3 +4x^2 > x + 4

Answers

The solution consists of all of the true intervals is −4 < x < −1 x > 1.

−4<x<−1 or x>1

Inequality Form: −4<x<−1 or x>1

Interval Notation: (−4,−1) ∪ (1,∞)

x^3 + 4x^2 > x + 4

Subtract x from both sides of the inequality.

x^3 + 4x^2 − x > 4

Convert the inequality to an equation.

x^3 + 4x^2 − x = 4

Move 4 to the left side of the equation by subtracting it from both sides.

x^3 + 4x^2>x+4

2 − x − 4 = 0

Factor the left side of the equation

(x + 4)(x + 1)(x − 1) = 0

If any individual factor on the left side of the equation is equal to, the entire expression will be equal to 0

x + 4 = 0

x + 1 = 0

x − 1 = 0

Set x + 4 equal to 0 and solve for x

x = −4

Set x + 1 equal to 0 and solve for x

What is inequality?

Inequality is the difference in social status, wealth, or opportunity between people or groups. People are concerned about social inequality.

x = −1

Set x + -1 equal to 0 and solve for x

x = 1

The final solution is all the values that make (x + 4)(x + 1)(x − 1) = 0 true

x = −4, −1, 1

Use each root to create test intervals.

x < −4

−4 < x < −1

−1 < x < 1

x > 1

Choose a test value from each interval and plug this value into the original inequality to determine which intervals satisfy the

inequality.
