Answer:

x = 5

Step-by-step explanation:

6*(2x+8) = 108

12x + 48 = 108

x =60/12

x = 5

Answer:

x = 5 units

Step-by-step explanation:

The area of a rectangle equals length times widths, therefore we can use the information from the question to make the following equation...

108 = (2x + 8)(6)

Now we just solve the equation and get...

108 = (2x + 8)(6)

108 = 12x + 48

12x = 108 - 48

12x = 60

x = 60 / 12

x = 5

Therefore, x = 5 units.

Sofia is a helper for the kindergarten class and is in charge of picking a video for their end-of-year party. To choose which type of movie they would like best, she decided to survey every other child entering a matinee for a cartoon called, “Three Pretty Princesses.” The total number of children surveyed was 40. What is wrong with the way she selected her sample? Check all that apply.
The sample of 40 children is too small to represent all kindergartners.
The sample was taken at a specific movie, which will skew data towards that type of movie.
The sample is likely to include a lot more girls than boys, since the movie title is “Three Pretty Princesses.”
The sample should include the adults with the children instead of only children.
The sample should include the other peer helpers in her grade to include a greater age range.

Which dimensions can create only one unique triangle?
A.) 3 angles measuring 75 degrees, 45 degrees, and 50 degrees
B.) 3 sides measuring 14 m, 11 m, and 18 m
C.) 3 angles measuring 40 degrees, 50 degrees, and 60 degrees
D.) 3 sides measuring 3 cm, 4 cm, and 8 cm

Answers

Answer:

B)

Step-by-step explanation:

A, C, and D multiple choice answers have no chance of becoming a triangle because the lengths don't add up to either 180 or 90. Also, Triangle B follows the rule that 2 sides and be greater than the other side.

Answer: Choice B)

3 sides measuring 14 m, 11 m, and 18 m

=================================================

Explanation:

Let's go through choices A through D to see which result in one unique triangle, or could produce (infinitely) many triangles, or produce no triangles at all.

Choice A produces no triangles at all. Why is this? The angles don't add up to 180. We see that 75+45+50 = 170. The three angles must add to 180 degrees for a triangle to form. Choice B produces one single triangle, which is why it's the final answer. The triangle inequality theorem can be used here to show that a triangle can be formed. The SSS (side side side) congruence theorem is then used to show that exactly one unique triangle is possible. Choice C is a similar story to choice A. We can rule it out. This time we have the angles add to 40+50+60 = 150 which is short of 180.Choice D can be ruled out too. The two sides a = 3 and b = 4 add to a+b = 3+4 = 7, but that's smaller than c = 8. We must have a+b > c to be true if we wanted to form a triangle. For more info, see the triangle inequality theorem.

Even if the angles did add to 180 (for either choice A or choice C), then we'd have infinitely many triangles and not one unique triangle. Think of dilating the triangles and how each dilated image retains the same angles. In other words, the triangles keep the same shape. Simply knowing the three angles is not enough info to create one unique triangle. We would need to know some info about the sides. This explains why AA or AAA is not a congruence theorem.

A man is trying to zombie-proof his house. He wants to cut a length of wood that will brace a door against a wall. The wall is 4 feet away from the door, and he wants the brace to rest 2 feet up the door. About how long should he cut the brace?

Answers

Answer:

Assuming you're rounding to the nearest tenth, he should cut the brace 4.5 feet long.

Step-by-step explanation:

Since this is a right triangle, you can use the a^2 + b^2 = c^2 easily.

You can use either 2 or 4 as the a or the b.

After filling in the equation, 2^2 + 4^2 = c^2, you can calculate it to find it is 4 + 16 = c^2.

If you add 16 + 4, you get 20. So now, you need to find the square root of 20 which is 4.4721 but if you round to the nearest tenth, you get 4.5^2.

He should cut the brace to 4.5 square feet.

I hope this helps :))
