Answer:
Step-by-step explanation:
There are no real factors of x^2+36 because the discriminant is -144, but if we include imaginary units it can be factored to
(x+6i)(x-6i)
ANSWERS
a. Yes, congruent. By SSS postulate
b. Yes, congruent. By AAA postulate
c. Yes, conguent. By SAS postulate
EXPLANATION
a. Sides MQ and MN are congruent as shown in the diagram. So are sides PN and PQ. Side PM is shared by both triangles so it must be congruent to both.
b. It is shown in the diagram which angles are congruent:
c. Angles DEC and AEB are <em>vertical angles</em> and they are therefore congruent. The two sides that form those angles are shown congruent in the diagram, so we have a side, the next angle and the next side: SAS postulate.

Answer: Table 3
A table of values x and y represents a linear function,
if the change in x is always proportional with the change in y:
For example:
x changes from 1 to 2, y changes from -3 to -5
that is, a change of 1 in the x-es, is a change of +2 in the y's.
x changes from 2 to 4, y changes from -5 to -9
that is, a change of 2 in x, is a change of +4 in the y's.
1, 2 and 2, 4 are proportional
Another way we can check that Table 3 is the only one representing a linear function, is the constant change in y:
as x takes the values : 1, 2, 3, 4, y becomes -3, -5, -7, -9
that is, a constant change of 1 in the x-es, means a constant change of +2 in the y's
Answer:
a = 5
b = 1.3
c = 6.3
Step-by-step explanation:
To find the values of a, b and C respectively, let's find a first by recalling that the diagonals of a rhombus are perpendicular to each other.
Therefore, the angle given as (14a + 20) = 90°
Solve for a
14a + 20 = 90
14a = 90 - 20
14a = 70
a = 70/14
a = 5
==>To find b, also recall that all sides of a rhombus are equal.
Therefore 3b + 4 = 13b - 9
Solve for b
4 + 9 = 13b - 3b
13 = 10b
13/10 = b
b = 1.3
==>Find value of c
c = a + b
c = 5 + 1.3
c = 6.3
