Answers

Answer:-77

Step-by-step explanation:cuz it is

Answer:

-77

Step-by-step explanation:

So with the first equation you are going to need to solve for "x". You are going to want to iqnore the secone expression till you solve for "x".

2x-1=13 add 1 on both sides   +1  +1 2x=14[tex]\frac{2x}{2}=\frac{14}{2}[/tex] Then, divide 2 on both sidesWhich would give you "x=7"

Now that you finish that solvign the first equation you are going to plug "7" into "x" in the expression shown below

[tex]-x^{2}-4x\\[/tex]    [tex]-(7)^{2}-4(7)[/tex] we are going to solve the first part multiplying 7 by itself[tex]-7*7=-49[/tex] then we are going to solve the second part multiplying-4*7[tex]-4*7=-28[/tex] now we are going to add them both which gives us this. -49+-28=-77

And that is how le9045 got -77.
