ANSWER IS <u><em>1080</em></u> because the paturn is to D'vide by 6
Step-by-step explanation:
A. 4x + 9 = 34
<u> - 9 - 9</u>
<u>4x</u> = <u>25</u>
4 4
x = 6.25
B. (x - 4)(x + 2) = 0
x - 4 = 0 U x + 2 = 0
<u> + 4 + 4</u> <u> - 2 - 2</u>
x = 4 x = -2
C. 2x² - 6x + 4 = 0
2(x²) - 2(3x) + 2(2) = 0
<u>2(x² - 3x + 2)</u> = <u>0</u>
2 2
x² - 3x + 2 = 0
x = <u>-(-3) +/- √((-3)² - 4(1)(2))</u>
2(1)
x = <u>3 +/- √(9 - 8)</u>
2
x = <u>3 +/- √(1)
</u> 2<u>
</u> x =<u> 3 +/- 1
</u> 2
x = <u>3 + 1</u> U x = <u>3 - 1</u>
2 2
x = <u>4</u> x = <u>2</u>
2 2
x = 2 x = 1

Answer:
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume of cylinder = πr^2h
Where
π is a constant whose value is 3.14.
r represents the radius of the cylinder.
h represents the height of the cylinder.
From the information given,
The radius of a cylinder is 7.8*10^-4 m.
The height of the cylinder is 3.4*10^-2.
Therefore,
Volume of cylinder =
3.14 × (7.8*10^-4)^2 × 3.4*10^-2
= 3.14 × 60.8*10^-8 × 3.4*10^-2
= 649.52784 × 10^- 10 m^2
The would be 3.5 because you have to multiply the two numbers.
