Answer:

x <  - 8

First answer is correct

Step-by-step explanation:

3 - (2x - 5) <  - 4(x + 2) \\ 3 - 2x + 5 <  - 4x - 8 \\ 3 + 5 + 8 <   +  2x - 4x \\ 16 <  - 2x \\  \frac{16}{ - 2}  <  \frac{ - 2x}{ - 2}  \\ x <  - 8

Answer:

x <-8

Step-by-step explanation:

3-(2x-5) < -4(x+2)

Distribute

3 -2x+5 < -4x-8

Combine like terms

8 -2x < -4x-8

Add 4x to each side

8 -2x+4x< -4x-8+4x

8+2x < -8

Subtract 8 from each side

8-8+2x< -8-8

2x<-16

Divide by 2

2x/2 < -16/2

x <-8

HURRY I WILL GIVE BRAINLIEST!!
nika2105 [10]
Hi there! 

The formula for the volume of a cone is V = 1/3(pi x r^2 x h). Using this formula, we can solve for the volume of the cone.

WORK:
V = 1/3(3.14 x 6.5^2 x 14)
V = 1857.31 / 3
V = 619.10 cm^3

ANSWER:
A) 619.10cm^3

Hope this helps!! :)

In a right triangle abc, cd is an altitude, such that ad=bc. Find ac, if ab=3 cm, and cd= square root 2 cm.
Mashcka [7]

      <u>ΔACB</u>                                               <u>ΔCDA</u>

AC² + BC² = AB²                           AD² + CD² = AC²  

          BC² = AB² - AC²                 BC² + CD² = AC²        (AD=BC is given)

                                                                 BC² = AC² - CD²

                         AB² - AC² = AC² - CD²         (both sides were = to BC²)

                         AB² + CD² = 2AC²

                         (3)² + (√2)² = 2AC²            (AB=3 and CD=√2 were given)

                          9  +   2    = 2AC²

                               11        = 2AC²

                                \frac{11}{2}        = AC²

                                \sqrt{\frac{11}{2} }     = AC

                                \frac{11\sqrt{2} }{2}      = AC
