Question

Wich expresion have a value of 180 when b=4? select all that apply. USE PEMDAS

Answer 1

So, to solve this we will have to Test by substituting the 4 into the equations given

`\begin{gathered} 18b\text{ - 179 +957 }(\cdot)/(\cdot)\text{ 87} \\ 18(4)\text{- 179 +957 }(\cdot)/(\cdot)\text{ 87} \\ 72\text{- 179 +957 }(\cdot)/(\cdot)\text{ 87} \\ 72\text{- 179 +11} \\ -96\\e\text{ 180 (not equal to 180)} \end{gathered}`
`\begin{gathered} (B)(33b)/(12)\text{ = }(33*4)/(12)\text{ = }11\text{ } \\ \text{ 11}\\e180(not\text{ equivalent to 180)} \end{gathered}`
`\begin{gathered} C)b^2\text{ + 120} \\ \text{ (4)}^2\text{ + 120 =136 } \\ \text{136 }\\e\text{ 180(Not equivalent to 180)} \end{gathered}`
`\begin{gathered} D)\text{ 51b - 24} \\ \text{ 51(4) - 24 } \\ \text{ 204 -24 = 180 This question is correction} \end{gathered}`

E) 11b + 187 -2756/13

11(4) + 187 - 212

44+187 - 212 = 19

19 is not equivalent to 180
