What is the surface area of this design? 8,8,8
Hi!
To find the surface area, we must first find the area of all of the faces and then add them together.
Because every face is the same size, the formula will be:
6(8 x 8)
6 represents the number of faces and 8 x 8 represents the formula to find the area of each.
6(8 x 8) =
6(64) =
384
The surface area of the cube is 384 square inches.
I hope this helps you!

One lane on a motorway is closed by cones for a distance of 1 mile. The cones are placed 4 feet apart. How many cones are used?
Answer:
1320 cones
Step-by-step explanation:
1 mile = 5280 feet
For every 4 feet, 1 cone is placed so
5280/4 = 1320
Therefore 1320 cones are used.

If a - b=7, what is also true?
A
B
C
D
Answer: B. a + (-b) = 7
Step-by-step explanation:
The answer is B. a + (-b) = 7. a + (-b) is the same thing with a - b.
A. a + b = -7
a - b = 7 means the differences of a and b is 7, choice A is talking about their sum, so it could not be true.
C. -a - b = 7
if you multiply -1 on both sides, you will get a + b = -7. Therefore, it will not be true.
D. b - a = 7
a - b = 7 means that a is 7 more than b. The choice d shows the opposite, which it states that b is 7 more than a. Therefore, it is not true.

The factorisation of the polynomial [tex]2x^3+8x^2+3x+12[/tex] can be done as [tex](2x^2+3)(x+4)[/tex].
What is a factor?A factor of n is a number that when multiplied by another number gives us the number n.
In order to factorise the given polynomial, we need to take the common terms out, therefore, the factorisation of the given polynomial can be done as,
[tex]2x^3+8x^2+3x+12[/tex]
Take 2x² as the common term from the first two terms and 3 from the last two terms,
[tex]2x^3+8x^2+3x+12\\\\= 2x^2(x+4)+3(x+4)\\\\=(2x^2+3)(x+4)[/tex]
Hence, the factorisation of the polynomial [tex]2x^3+8x^2+3x+12[/tex] can be done as [tex](2x^2+3)(x+4)[/tex].

Let f(x) = x – 4 and g(x) = x^2 – 16.
Perform the function operation f(x) + g(x) and then find the domain.
Answer:
f(x) +g(x) = x^2 +x -20
domain: all real numbers
Step-by-step explanation:
The sum of two polynomial functions is found by adding the terms of each function definition:
f(x) +g(x) = (x -4) +(x^2 -16)
f(x) +g(x) = x^2 +x -20

Step-by-step explanation:
Median is the middle number from least to greatest meaning that 7 is the median.
Answer:
7
Step-by-step explanation:
Let's first sort it form lowest to highest. So it's going to be 3,4,5,6,7,7,8,9,9. Now, we ifnd the middle ofit, which is 7. The middle number of the sequence is 7 becaue there are 9 numbers total so that means that the 5th number is the median.

Suppose c and d vary inversely, and d=2 when c=17.
a. Write an equation that models the variation.
b. Find d when c=68.
Answer:
a. x - cd = 0
b. d = 1 / 2
Step-by-step explanation:
d = 2
c = 7
a.
c is inversely proportional to d,
c ∝ 1 / d
This inversely proportional need to be removed by using a variation / variable.
Let the variable be " x ".
c = x / d
Multiply d on both sides,
cd = x
x = cd
Subtract cd on both sides,
x - cd = 0
Hence, the equation is " x - cd = 0 ".
b.
By using the equation,
x - cd = 0
Add cd on both sides,
x = cd
c = 17, d = 2
x = 17 * 2
x = 34
To find d, when c = 68.
x = cd
34 = 68 * d
Divide 68 on both sides,
34 / 68 = d
1 / 2 = d
d = 1 / 2

Hey there!
=> n + 652 = 17 { Substract 652 from both sides}

=> n = 17 -652
=> n = -635
Therefore, N = -635

What is the slope of a line perpendicular to the line whose equation is 6x-10y=140. Fully simplify your answer.
y=14
10y=140
Divide both sides by 10.
y=
10
140
Divide 140 by 10 to get 14.
y=14
The slope of a line perpendicular is -5/3 to the line whose equation is 6x-10y = 140.
What is the slope of the line?The slope of a line is defined as the inclination of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Make the following equation in slope-intercept form:
y = mx + b
where m denotes the slope and (0,b) denotes the y-intercept (the point at which x = 0).
The given equation is:
6x - 10y = 140
-10y = - 6x + 140
Divided by -10 into both sides of the equation,
y = (6/10)x + 140/(-10)
y = (3/5)x -14
Here m = 3/5, b is (0,14)
The slope of this line is 3/5.
The slope of all of its perpendicular lines is (-1/m), which is the negative reciprocal of slope m.
Therefore, the slope of all perpendicular lines is (-5/3).

If I'm wrong, then I'm sorry.
The product of (−35)∙(−1). (5) will be 105. It is obtained by multiplying the term one by one.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
We can utilize multiplication for a number of common tasks, such as figuring out how much it will cost to buy several identical things, calculating sales tax, and figuring out area and other geometric measurements.
It is given that,
=(−35)∙(−1).5
Multiply the term step by step as
=(−35)∙(−1).5
The multiplication of two negative terms gives a positive value.
=(35)5
=105
Thus, the product of (−35)∙(−1). (5) will be 105. It is obtained by multiplying the term one by one.

Answer:
4π : 9π
Step-by-step explanation:
→ Find the area of circle with radius 8
π × 8² = 64π
→ Find the area of circle with radius 12
π × 12² = 144π
→ Simplify ratios
64π : 144π ⇒ 4π : 9π
