Answer:
The answer to your question is:
x 1 = -0.65
x2 = 7.65
Step-by-step explanation:
Equation -x² + 7x + 5 = 0
a = -1
b = 7
c = 5
Quadratic formula x = -b ±√(b² -4ac) / 2a
x = - 7 ± √(7² -4(-1)(5) / 2(-1)
x = -7 ± √(49 + 20) / -2
x = -7 ± √69 / -2
x = - 7 ± 8.3 / -2
x1 = -7 + 8.3 / -2 x2 = -7 -8.3 / -2
x 1 = -0.65 x2 = 7.65

Answer:
(2) 22
Step-by-step explanation:
In the given triangle MNP, the medians are straight lines drawn from the angle to opposite side so as to divide the side into equal parts.
PS = 8 and QS = 3, thus;
PS = NS = 8 (congruent property of ΔRSN and ΔQSP)
QS = SP = 3 (congruence property)
So that,
NQ = NS + SQ
= 8 + 3
= 11
PR = PS + SR
= 8 + 3
= 11
Thus;
NQ + PR = 11 + 11
= 22
Therefore, NQ + PR = 22
