All the shapes except the circle & heart are polygons
Answer:
Use the order of operations in reverse and remember that dividing or multiplying by a negative reverses the inequality
Explanation:
The order of operations is PEMDAS in reverse it is PESADM ( if you lose your cell phone in PE you are a SAD M(am)
Remember multiply or dividing by a negative reverses the value of the quality being divided or multiplied.
Just do the order of operations in reverse as in solving an equation always doing the opposite. Then remember to reverse the inequality sign whenever the inequality is multiplied or divided by a negative.

Answer:
5z^(-5/3)
Step-by-step explanation:
The rules of exponents being used here are ...
![\sqrt[n]{a}=a^{1/n}\\\\\dfrac{a^b}{a^c}=a^{b-c}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%3Da%5E%7B1%2Fn%7D%5C%5C%5C%5C%5Cdfrac%7Ba%5Eb%7D%7Ba%5Ec%7D%3Da%5E%7Bb-c%7D)
Using these rules on the given expression, we find ...
![\dfrac{10\sqrt[3]{z}}{2z^2}=\dfrac{10}{2}z^{1/3-2}=\boxed{5z^{-5/3}}](https://tex.z-dn.net/?f=%5Cdfrac%7B10%5Csqrt%5B3%5D%7Bz%7D%7D%7B2z%5E2%7D%3D%5Cdfrac%7B10%7D%7B2%7Dz%5E%7B1%2F3-2%7D%3D%5Cboxed%7B5z%5E%7B-5%2F3%7D%7D)
Answer: 2s + 1
Explanation:
1) Given expression: 6s² - 7s- 5 = (3s - 5) ( )
2) The missing factor ( ) is such that when it is multiplied by (3s - 5) the product is 6s² - 7s- 5.
3) Since the first term of the first factor starts with 3s, the first term of the second factor shall be 2s (since they have to yield 6s²). Then, you can write:
6s² - 7s- 5 = (3s - 5) (2s + )
4) The second term of the missing factor is positive because the product (+)(-) = (-) which is the sign of the third term of the polynomial.
5) The second term is such that when multiplied by - 5 is equal to the last term of the polynomial (also - 5), so this second terms is +1.
And you get: 6s² - 7s- 5 = (3s - 5) (2s + 1)
6) You can expand, using distributive property to confirm the result:
(3s - 5) (2s + 1 ) = (3s)(2s) + (3s)(1) - (5)(2s) -(5)(1) = 6s² - 7s- 5, which confirms the result.
1st Bagel; $0.79. 2nd Bagel; $0.67. 3rd Bagel; $0.70. 4th Bagel; $0.75. So B would be the correct answer, given 67¢ is cheaper ;)))))))
