Answer:

B.  x  = -5 +/- √30.

Step-by-step explanation:

2x^2 + 20x = 10

2(x^2 + 10x) = 10

2[ (x + 5)^2 - 25 ] =10

2(x + 5)^2 - 50 = 10

2(x + 5)^2 = 60

(x + 5)^2 = 30

x + 5 =  +/- √30

x  = -5 +/- √30.

Given that S is the centroid of triangle MNO, find SQ.
DochEvi [55]

Answer:

First, we need to calculate for x. Since,

MP = PN

Thus,


3x-4 = x+4

2x = 8

x = 4


Next, we calculate for MS 

MS = 2x + 2 = 10


Since, MS = 2SQ

10 = 2SQ

Then,

SQ = 5 units


Therefore, the correct answer is B.

Find the lateral area of the cone in terms of π.
Andreyy89

Answer:

15\pi\ cm^{2}

Step-by-step explanation:

we know that

The lateral area of the cone is equal to

LA=\pi rl

where

r is the radius of the base

l is the slant height

we have

r=3\ cm

Applying the Pythagoras Theorem find the slant height

l^{2}=3^{2} +4^{2}\\ \\l^{2}=25\\ \\l=5\ cm

substitute in the formula

LA=\pi (3)(5)=15\pi\ cm^{2}
