Find the solutions to x^2-10+36=0

Mathematics
1 answer:
klemol [59]4 years ago
5 0

Answer:

Only 6

Step-by-step explanation:

We need to factor the equation to find the solution.  TO factor we need to find what times what = 36, and what plus what equals -12.

-6 times -6 = 36

and -6 + -6 = -12

So this can be factored into

(x-6)(x-6)=0

We can find the solution by setting each parentheses equal to zero.

x-6 = 0

x = 6

So the only solution is 6

I attached an image that shows an example of factoring.

How is finding the unit rate helpful before graphing a proportional relationship
Paul [167]
One example, take the conversion fact that there are 5 miles for every 8 km.

Now if we want to work out how many kilometres in 6 miles, the conversion above is not going to help straight away.

We first need to find how many kilometres in ONE mile [which is the unit rate]

5 miles = 8 kilometres
1 mile = 8/5 kilometres
1 mile = 1.6 kilometres

Once we know the unit rate, we can then work out the number of kilometres for any number of miles.

For example:
6 miles = 6×1.6 = 9.6 kilometres
25.5 miles = 25.5 × 1.6 = 40.8 kilometres

Examine the diagram.
wolverine [178]

Answer:

m\angle 1 =60.75^\circ \\m\angle 2 =119.25^\circ

Step-by-step explanation:

From the diagram:

m\angle 1 =60.75^\circ $(Corresponding Angles)\\

Now Angle 1 and Angle 2 are on a straight line, therefore:

m\angle 1 +m\angle 2 =180^\circ $(Linear Postulate)\\Since m\angle 1=60.75^\circ\\60.75^\circ +m\angle 2 =180^\circ\\m\angle 2=180^\circ-60.75^\circ\\m\angle 2 =119.25^\circ

puteri [66]
F(x) is most likely the f(f(x)x) where f(x) is g(x))f)) and composition can be 69 + 46 which is the total of 137
