A regular polygon has all equal sides and angles, a quadralateral means it has four sides, you are correct.
1. no because 2x+10 is not equal to 2x+7
2. no. you cant add una like terms so 4x+4 doesn’t equal 8x
3. yes. the terms still retain their same value although they are not in the same order
4. yes. when u distribute the -3, you get -3x-6 which is of course equal to -3x-6
Answer:
The area of silver charm is 33.75 square mm.
Step-by-step explanation:
We are given the following in the question:
The silver and golden charms are similar isosceles triangles.
Gold charms:
Base = 9 mm
Area = 15 square mm
Silver charm:
Base = 9 mm
Property of similar triangles:
- If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides.
Using this property we can write:
![\dfrac{\text{Area of gold charm}}{\text{Area of silver charm}}=\dfrac{(\text{Base of gold charm})^2}{(\text{Base of silver charm})^2}\\\\=\dfrac{15}{\text{Area of silver charm}}=\dfrac{6^2}{9^2}\\\\\text{Area of silver charm} = \dfrac{15\times 9^2}{6^2} = 33.75\text{ mm}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BArea%20of%20gold%20charm%7D%7D%7B%5Ctext%7BArea%20of%20silver%20charm%7D%7D%3D%5Cdfrac%7B%28%5Ctext%7BBase%20of%20gold%20charm%7D%29%5E2%7D%7B%28%5Ctext%7BBase%20of%20silver%20charm%7D%29%5E2%7D%5C%5C%5C%5C%3D%5Cdfrac%7B15%7D%7B%5Ctext%7BArea%20of%20silver%20charm%7D%7D%3D%5Cdfrac%7B6%5E2%7D%7B9%5E2%7D%5C%5C%5C%5C%5Ctext%7BArea%20of%20silver%20charm%7D%20%3D%20%5Cdfrac%7B15%5Ctimes%209%5E2%7D%7B6%5E2%7D%20%3D%2033.75%5Ctext%7B%20mm%7D)
Thus, the area of silver charm is 33.75 square mm.
Answer:
a and b
Step-by-step explanation:
Answer:
The answer to your question is
She ate 8 grapes
She gave to Tom 12 grapes
She has left 4 grapes
Step-by-step explanation:
Data
total grapes = 24
Portion eaten = 1/3
Portion given = 3/4
Process
1.- Divide 24 by three
24/3 = 8
Jenny ate 8 grapes
2.- Grapes left
24 - 8 = 16
- Divide 16 by 4
16/4 = 4
She gave to Tom 4 x 3 = 12 grapes
3.- The grapes she left were
24 - 8 - 12 = 4
