Solve the inequality for x.<br> 7x-26&lt;-5(2-3x)
Masja [62]

Answer:

x > 2

Step-by-step explanation:

7x-26<-5(2-3x)

first write out the equation

7x-26<-10 +15x

then solve the -5(2-3x)

by multiplying -5 by 2 and -5 by 3x which will give the answer -10 and 15x

7x-15x<-10+26

Now put the numbers with X first and since we moved the (+15x) into the otherside we change its sign to (-15x)

and because we put the (-26) into the otherside we do the same thing and change it into (+26)

-8x<16

Now we combine the same numbers so 7x-15x and -10+26

Next we divide both sides by (-8)

so (-8x÷-8) and (16÷-8)

and because we divided with a negative number (-8)

and we have an inequality( < ) we flip the sign from smaller than to greater than.

and so the final answer is x>2

or x is greater than 2

A cylinder has a radius of 4x + 2 and a height of 5x + 4. Which polynomial in standard form best describes the total volume of t
Olenka [21]
Area of the base = pi*(4x+2)^2 = pi*(16x^2 +16x +4)

volume of cylinder = pi*r^2 *h 

V = pi *(16x^2 +16x +4)(5x+4) = pi*(80x^3 +80x^2 +20x +64x^2 +64x +16) = 

= pi*(80x^3 +144x^2 +84x +16)

than we consider it without pi so result choice A. is right sure 

hope helped

For brett's birthday his mother gave out colorful birthday hats that were cone shaped. the opening of the bottom of the hat was
nika2105 [10]
The volume of cone is calculated by the formula V= \frac{1}{3} \pi R^2H, where H is a height of cone and R is a radius of the bottom.
In your case, R=3 cm and R=7 cm. Then V= \frac{1}{3} \pi* 3^2*7= \frac{63\pi}{3} =21\pi.
Answer: The volume of candy is 21π.
