You are scheduling a new delivery route and you need to find out how long it would take a drive out to complete the route you st

larisa [96]

The delivery route took 4 hours and 15 minutes.

Because 9:50 + 4 hours is 1:50

1:50 + 15 minutes is 2:05

Hope this helps! Have a great rest of your day :)

This drawing shows an Isosceles triangle. Work out the size of angle a.

antiseptic1488 [7]

50 degrees

All triangles have 180 degrees total.

Since it’s an isosceles triangle, the 2 bottom angles are congruent; thus, they have the same angle measurement.

Now just subtract the two angles from 180 to get the third angle.

180 - 65 - 65 = 50

Find the solution of the square root of the quantity of x plus 2 plus 4 equals 8, and determine if it is an extraneous solution

Iteru [2.4K]

Consider the equation:

$\sqrt{x+2}+4 = 8$

Subtracting '4' from both the sides of the equation, we get as

$\sqrt{x+2}+4-4= 8-4$

$\sqrt{x+2}= 4$

Squaring on both the sides of the equation, we get

$(\sqrt{x+2})^2 = (4)^2$

$x+2 = 16$

Subtracting '2' from both the sides of the equation, we get

$x+2-2=16-2$

x=14

Since, An extraneous solution is a solution that arises from the solving process that is not really a solution at all. But, in this equation x=14 is the solution of the given equation.

Hence, it is not an extraneous solution.
