Answer:

when this quadratic is equal to 0

3(3x^2+13x+14)=0

3(3x+7)(x+2)=0

3 is not equal to 0

therefore (3x+7) or(x+2)=0

OLEGan [10]
N and m are numbers 3 units apart

n + 3 = m
n = m - 3

Product:

m(m-3) = 108 (ANSWER)
m^2 - 3m - 108 = 0
(m-12)(m+9)=0

m = 12(greates) and -9(void)

n = m - 3
n = 12 - 3
n = 9


therefore the two numbers are 9 and 12

The proof that AMNS AQNS is shown.
FrozenT [24]

Answer:

The answer is "MS and QS".

Step-by-step explanation:

Given ΔMNQ is isosceles with base MQ, and NR and MQ bisect each other at S. we have to prove that ΔMNS ≅ ΔQNS.

As NR and MQ bisect each other at S

⇒ segments MS and SQ are therefore congruent by the definition of bisector i.e   MS=SQ

In ΔMNS and ΔQNS

MN=QN       (∵ MNQ is isosceles triangle)

∠NMS=∠NQS     (∵ MNQ is isosceles triangle)

MS=SQ         (Given)

By SAS rule, ΔMNS ≅ ΔQNS.

Hence, segments MS and SQ are therefore congruent by the definition of bisector.

The correct option is MS and QS
