Answer:

(x-3) is the factor of polynomial x2 + 6x + 9

and it's zero is -3

Step-by-step explanation:

by solving it we get ;

=

x {}^{2}  + 6x + 9

=

x {}^{2}  + 3x + 3x + 9

=

x(x + 3) + 3(x + 3)

=

(x + 3) {}^{2}

now, equating it with 0, we get

=

(x + 3) {}^{2}  = 0

=

x + 3 = 0

=

x =  - 3

so, the factor is ( x + 3 )

An angle measures 10 more than four times a number. It’s supplement is two more than three times the number. What is the measure
kiruha [24]

Answer:

4x +10 + 3x +2 = 180 (since they're supplementary, the angles together =180)

7x +12 =180  (combine like terms on left side, and subtract 12 from both sides)

7x = 168 (divide both sides by 7 to isolate x)

x= 24

angle 1 = 4(24)+10 (plug x into the expression for each angle, and solve)

..................96 +10

angle 1 = 106 degrees (the measure of the first angle)

angle 2 = 3(24) +2

..................72 +2

angle 2 = 74 (the measure of the second angle)

106 +74 =180 (the two add up to 180, so they're supplementary)

8. What do you know about triangles PDX and triangle CRX? Justify your answer.
s2008m [1.1K]
If segment PD is parallel to segment CR then triangle PDX is similar to triangle CRX, due to angle PXD and angle CXR being congruent by the vertical angle theorem, and angle PDX and angle CRX being congruent by the alternate interior angle theorem, these 2 triangles are similar by the A.A similarity postulate.

Step-by-step explanation:

Hypotenuse of a right angle triangle from pythagoras theorem is given by

h²=b²+a²

Making h the subject

h=√(b²+a²)

Where h is hypotenuse, b is base and a is the other side of a triangle

10²+24²=676

√676=26 units

72²+21²=5625

√5625=75 units

12²+35²=1369

√1369=37 units

18²+80²=6724

√6724=82 units

105²+100²=21025

√21025=145 units

16²+30²=1156

√1156=34 units
