Answer:

x = -2

TU = 4

UB = 2

Step-by-step explanation:

you can add x^2 with 4x+10 and equate it to 6:

x^2 + 4x + 10 = 6

x^2 + 4x + 4

then u can use the roots formula : x = (-b ± √ (b2 - 4ac) )/2a

so it'll be x = {-4±[√16 - 4(4)]}/2

x= -2

then u can substitute it and find TU and UB

TU= (-2)^2 = 4

UB= 4(-2)+10 = 2

Help me please I would really appreciate it

Step-by-step explanation:

The coordinates of the points are P1(2, 2) and P2(10, 2). The distance <em>d</em><em> </em> between these two points are given by

$d = \sqrt{ {(x\frac{}{2} - x\frac{}{1} ) }^{2} + ({y\frac{}{2} - y\frac{}{1}) }^{2} } \\ = \sqrt{ ({10 - 2})^{2} +( {2 - 2)}^{2}} \\ = 8$

Write an equation to represent the measures of the angles.

Rus_ich [418]

The angle x and the angle 18 degrees combine to form a right angle. The two angles add to 90 degrees

If you want to solve for x, then subtract 18 from both sides

x+18 = 90

x+18-18 = 90-18
