There zeros of a function mean the x-intercepts. simpler way: At what x-values does the graph of the equation intersect the x-axis.

I don't know the if the last term of your function is +1 or -1 , so I did both for you using desmos graphing calculator. 

You can also use quadratic formula, and do the algebra, and see if you get the same answer.

Answer:

4 hours. 1 3/4 is about 2, and 2 1/4 rounds to 2. 1/4 would round to 0, but it would not affect the estimate's accuracy much because we rounded up by 1/4 on 1 3/4 already. Philipe spent about 4 hours on activities.

Answer:

x = 145°

Step-by-step explanation:

We know that y = 98°, so we can find ∠DBC:

180°-y = ∠DBC

180°-98° = 82°

We also know that z = 63°, therefore we can apply <u>exterior angle of triangles</u> to find x.

∠DBC + z = x

82°+63° = x

x = 145°
