If the sidewall of a cubic structure have length 7m , then find the total surface area.
is this jhit right?​

Answer:

i think the ans is 4(-x-1) = 12

Step-by-step explanation:

Answer:

1) [tex]3x^{2}[/tex]-19x-14

2) x=0, x=3

Step-by-step explanation:

1) (3x+2)(x-7)

Distribute the 3x to both x and -7, as well as the 2 to both x and - 7.

[tex]3x^{2}[/tex] - 21x + 2x -14

Combine like terms

[tex]3x^{2}[/tex] - 19x - 14

2)

In order to find the factors of x, set the expression equal to 0.

[tex]3x^{2}[/tex] - 9x = 0

Factor out the highest common multiple (3x)

3x(x-3) = 0

In order for x to satisfy the equality, you must either have a 0 in the parenthesis -> (x-3)=0 -> x =3

Or 3x = 0 -> x = 0

i  help you

Answer:

Step-by-step explanation:

First you would make the equation

(1/2x - 1/4)(5x^2 + 6)

afterwards you would multiply like normal binomials\

5/2x^3 + 3x - 5/4x^2 - 6/4

Then simplify

5/2x^3 - 5/4x^2 + 3x - 3/2

Remember to put them in order from the most roots to the least.

Answer:

This means that the rate of change of your position is negative and you have a negative velocity. A negative velocity does not mean that you are slowing down

Step-by-step explanation:

The meaning to have a negative change is, it is decreasing over time.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

We have to explain the meaning to have a negative change.

Hence, We get;

A positive rate of change means that the quantity you are measuring is increasing over time, and a negative rate of change means that it is decreasing over time.

Thus, The meaning to have a negative change is, it is decreasing over time.

Answer:

39

Step-by-step explanation:

Answer:

39

Step-by-step explanation:

the answer is going up by the numbers 1,2,3,4...

you start with 4 and go up by 2

you then get 6 that's when you count up 3

you get 9 and then count up 4

which is 13 count up 5

18 count up 6

24 count up 7

31 count up 8

Answer:

x = -2

Step-by-step explanation:

2(3x - 5) + 4 = -18

Distribute the 2

6x - 10 + 4 = -18

6x - 6 = -18

Add 6 to both sides

6x = -12

Divide both sides by 6

x = -2

Check:

2(3x - 5) + 4 = -18

substitute x = -2 into the original equation

2(3(-2) - 5) + 4 = -18

2(-6 - 5) + 4 = -18

2(-11) + 4 = -18

-22 + 4 = -18

-18 = -18

So x = -2 is true.

Answer:

x=-2

Step-by-step explanation:

2(3x-5)+4=-18

We move all terms to the left:

2(3x-5)+4-(-18)=0

We add all the numbers together, and all the variables

2(3x-5)+22=0

We multiply parentheses

6x-10+22=0

We add all the numbers together, and all the variables

6x+12=0

We move all terms containing x to the left, all other terms to the right

6x=-12

x=-12/6

x=-2

Answer:

28.27 ft²

Step-by-step explanation:

[tex]A=\pi r^2[/tex] where [tex]r[/tex] is the radius

Plug in 3 for the radius

[tex]A=\pi (3)^2\\A=9\pi[/tex]

[tex]A=28.27[/tex] (approximate answer when rounded to the nearest hundredth)

Therefore, the area of the circle is 28.27 ft².

I hope this helps!

Answer:

exact area: 9 ft²

approximate area: 28.3 ft²

Step-by-step explanation:

An area cannot be in feet. It must be in a square unit such as square feet.

A = r²

A = ()(3 ft)²

A = 9 ft²

A = 9(3.14159) ft^2 = 28.3 ft²

Answer:

exact area: 9 ft²

approximate area: 28.3 ft²

Answer:

46

Step-by-step explanation:

110+6x=386

Answer: 46 times

Step-by-step explanation:

Since $110 is the constant and 6 is the coefficient because it is changing with each time he rents a tennis ball. The equation is 110+6t=386 where t in this case can represent (return groundstrokes)

110+6t=386 solve for t

6t=276

t=46

So he can return ground strokes 46 times
