The value is of this equation is -3.75
i can only help you with the volume of #5.
So the volume of a cylinder is = πr²h.
First , put the numbers in the equation.
π(6)² (14)
Next you solve.
π(6)²(14) = 36 (14) π = 504π
V= 504π
Answer:
Step-by-step explanation:
This is pretty simple once you get used to this
First set it equal to the original and the negative one
(>_) is the bigger and equal to part
4x+5>_45 or 4x+5>_-45
Then solve for x for both
4x>_40. 4x>_-50
X>_10 X>_-25/2
(5) Angle ADC is the sum of angles ADB and BDC.
(6) Yes, because lines AG and EC form two pairs of vertical angles, including ADC and EDG, as well as ADE and CDG.
(7) Angle HJK is clearly a right angle, and a right angle has measure 90°.
