5 shirts for $21
the 6 deal would be $4.25 for each shirt
4 deal would be $4.50 for each shirt
and the 5 deal is the cheapest because its $4.20 for each shirt
Answer:
i felt that
Step-by-step explanation:
This would be the Transitive Property of Congruence.
This property of congruence states that if two angles/segments/polygons are both congruent to something else, then they are congruent to each other.
Hope this helps! :)
Answer:
The value of x should be greater than 3.
Step-by-step explanation:
Given that,
The AB is 12 units.
The AC is 15 units.
We need to find the value of BC.
Based on the above information, the calculation is as follows:
As we know that
The sum of two sides length is always more than the 3rd one.
Based on this,
12 + 15 > x
x < 27
15 + x >12
x >-3
12 + x > 15
x >3
Answer:

Step-by-step explanation:
<u>Factoring</u>
We need to recall the following polynomial identity:

The given expression is:

To factor the above expression, we need to find a and b, knowing a^3 and b^3. a is the cubic root of a^3, and b is the cubic root of b^3:
![a=\sqrt[3]{x^6}=x^2](https://tex.z-dn.net/?f=a%3D%5Csqrt%5B3%5D%7Bx%5E6%7D%3Dx%5E2)
![b=\sqrt[3]{64y^3}=4y](https://tex.z-dn.net/?f=b%3D%5Csqrt%5B3%5D%7B64y%5E3%7D%3D4y)
Now we apply the identity:
![x^6– 64y^3=(x^2-4y)[(x^2)^2+(x^2)*(4y)+(4y)^2]](https://tex.z-dn.net/?f=x%5E6%E2%80%93%2064y%5E3%3D%28x%5E2-4y%29%5B%28x%5E2%29%5E2%2B%28x%5E2%29%2A%284y%29%2B%284y%29%5E2%5D)
Operating:
![x^6– 64y^3=(x^2-4y)[x^4+4x^2y+16y^2]](https://tex.z-dn.net/?f=x%5E6%E2%80%93%2064y%5E3%3D%28x%5E2-4y%29%5Bx%5E4%2B4x%5E2y%2B16y%5E2%5D)
The remaining factors cannot be factored in anymore. Thus the completely factored form is:
