Answer:

157.6

Step-by-step explanation:

Use PEMDAS! In this rule, it is stated that we should always add/subtract before multiplying/dividing. Also, whatever you do on one side of an equation, you do to another. Therefore, in order to get rid of the -2/5, add 2/5 so we can get rid of it. We also (according to the rule), have to add it to the other side in order to balance out. So add the 2/5 to 39. Then the other side is now 39.4. Now we have to get x by itself. Divide both sides by 1/4 (or multiply by 4 on both sides) in order to get x=157.6

For this problem all we need to do is ignore everything except the equation and the input (5.5)

so the steps for this problem are below
we need to plug in 5.5 into our equation as it's our input of time to get our output of height
$t(5.5) = - 16(5.5) {}^{2} + 125(5.5)$
after simplifying you get

remember to square the 5.5 first (order of operations)

$t(5.5) = - 16(30.25) + 687.5$

simplify just a tad more and we get this as the final answer
$t(5.5) = - 484 + 687.5 = 203.5$
$203.5 \: ft$
