Answer:

all x are the solution

Step-by-step explanation:

x - 4×3 - 4×(-2x) = 3×3x + 3×4

x - 12 + 8x = 9x +12

9x + 12 = 9x + 12

9x = 9x

(0 = 0)

no matter which number we take for x the equation will always be correct

ex. x = 3 : left : 9×3 = 27

right : 9×3 = 27

Can someone help me please

Dafna1 [17]

Answer:

none

Explanation:

Fill in each option for x individually.

I) 9 $\leq$ -10 - 4(-1)

II) 9 $\leq$ -10 - 4(-3)

III) 9 $\leq$ -10 - 4(-2)

Then, simplify the right side of each inequality.

I) 9 $\leq$ -6

II) 9 $\leq$ 2

III) 9 $\leq$ -2

Each of these inequalities are flase. 9 is not less than or equal to any of these values, so the answer is none.

A cylinder has a base with a radius of 5 cm and a height of 15 cm. What is the volume of the cylinder? (Use π = 3.14.) A. 471 cm

eduard

The formula for volume is
$V=\pi r^{2}h$
We plug in:
$V=\pi (5)^{2}(15)$
$=\pi (25)(15)$
$=375\pi$
$=375*3.14=1177.5$
