2(3x – 5) = 8
what is the x?

Answers

Answer:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

2*(3*x-5)-(8)=0

2 • (3x - 5) -  8  = 0

Pull out like factors :

6x - 18  =   6 • (x - 3)

6 • (x - 3)  = 0

Solve :    6   =  0

Add  3  to both sides of the equation :  

x = 3

Answer: x = 3

Step-by-step explanation:

2(3x-5)=8

first, you multiply 2 by 3x and -5.

6x-10=8

since we want 6x by it’s self we add 10 to its self and add it to 8 as well.

6x = 18

now we divide 6 to both 6x and 18.

x = 3

All solutions that lie on f(x)

All positive solutions

pls answer fast!

Answers

Answer:

C. All positive solutions

Step-by-step explanation:

We can see that the solutions (or points that intercept the x-axis) are at 0,1 and 0,2. We can simplify this to just 1,2 if you would like, but nevertheless all x-intercepts are positive.

x = 1 and x = 2 are the solutions of the parabola shown.

All whole number and positive solutions.

Options C and D are correct.

How do you find the opening of a parabola?

There is an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.

When we are looking for a solution to a graphical function f(x), we basically mean the x-intercepts of the graph.

The place where the graph cuts/crosses the x-axis are the solutions of the graph. The y point will always be 0 at those designated x values.

Looking at the graph, we see that:

x = 1 and x = 2

are the solutions of the parabola shown.

All whole number and positive solutions.

Options C and D are correct.

Find the lateral surface area of the cylinder. Round your answer to the nearest tenth.

Answers

Answer:-

Given:-

Radius (r) of the cylinder = 10 ft.

Height (h) of the cylinder = 6 ft.

To Find:-

The lateral surface area of the cylinder.

Solution:-

We know,

[tex] \dag [/tex] Formula of lateral surface area of cylinder is 2πrh.

So, Lateral surface area of the cylinder = 2 × 3.14 × 10 × 6

Lateral surface area of the cylinder = 376.8 = 377 sq. ft.

The lateral surface area of the cylinder is 377 sq. ft. [Answer]

Answers

Answer:

Step-by-step explanation:

36 / 3 = 12

12 = 4 x 3

V = L x W x H

= 4ft x 3ft x 3ft

=

Since Geoffrey wants to build a planter with a height of 3ft & a volume of 36ft^(3), the base of the planter should have an area of 12ft^(2).
