Answer:
c³ + cd³ + 3c²d + 3cd²
Step-by-step explanation:
(c+d)^3 is worded as c plus d quantity cubed which doesn't mean you cube everything inside. It means you multiply the quantity by itself 3 times.
(c+d)(c+d)(c+d)
You can only multiply 2 at a time so do the first two then the result and the third one.
Distribute everything in one quantity to the other so c*c = c^2 and c*d = cd
= (c^2 + 2cd + d^2)(c+d)
= c^3 + c^2d + 2c^2d + 2cd^2 + cd^2 + cd^3
Combine like terms
= c³ + 3c²d + 3cd² + cd³
which of the following situations describes a postive number
Answer:
B. Going up the elevator 14 floors
Step-by-step explanation:
Choice A can't be right because you are going below sea level (negative).
Choice C can't be correct either because the word "losing" let's you know that it's negative.
Choice D isn't right because if you are taking $20 from your checking account, it would be a negative number.
Hope this helps!

4x - 6 + 5x +1
9x - 5
Have a good day
Answer:
9x - 5
Step-by-step explanation:
To get the this answer you would combine like terms. 4x and 5x are like terms, so you would combine them and get 9x. -6 and 1 are like terms, so you would combine those and get -5.

Angel got a job at in-n-out burger. He works 20 hours a week and makes $15.75 an hour. How much will his
paycheck be after 2 weeks of work (before uncle sam takes away taxes
Multiply hours per week by hourly pay rate:
20 x $15.75 = $315.00 per week
Multiply by 2 weeks:
$315 x 2 = $630
After 2 weeks paycheck is $630
Answer:
630
Step-by-step explanation:
15.75 x 20 = 315
315 is how much Angel makes in one week
315 x 2 = 630
630 is how much he will make in two weeks
The 2 signifies how many weeks have been worked
Find the area for all of these numbers
Answer:
The Answer is 29cm
Step-by-step explanation:
The area of this shape is made from two shapes.
Shape one is a rectangle with the dimensions 2cm by 4cm
2x4 = 8
So the area of rectangle 1 is 8
The other rectangle has the dimensions 4cm by 7cm
Because you have to account for the other triangle not being there (solved)
4x7 = 21
21+8
29cm

What is the inverse of v(x)= -3/4x - 1/3?
Step-by-step explanation:
v(x) = y = -3/4x - 1/3
y + 1/3 = -3/4x
x = -4/3 × (y + 1/3)
you see ? we only need to show how we calculate x out of y (instead of the normal direction of y or of x).
and to follow naming standards we now simply switch x and y, so that the inverse function is indeed again a function of x
y = -4/3 × (x + 1/3) = -4x/3 - 4/9

the perimeter of a rectangular tray is 60in the length of the tray is double the width of a tray determine the dimensions of the rectangular tray
Answer:
Step-by-step explanation:
Width = w
Length = double the width = 2*w = 2w
Perimeter of rectangular tray = 60 in
2*(length + width) = 60
2*( 2w + w) = 60
2*3w = 60
6w = 60
Divide both sides by 6
w = 60/6
w = 10 in
length =2w = 2*10 = 20
length = 20 in
Width = 10 in

Answer:
d = 3
Step-by-step explanation:
(7d+3)/4 = 6
Multiply each side by 4
(7d+3)/4*4 = 6*4
(7d+3) = 24
Subtract 3 from each side
7d+3-3 = 24-3
7d = 21
Divide by 7
7d/7 = 21/7
d = 3

Answer:
f(- 10) = 74
Step-by-step explanation:
To find f(- 10) , substitute n = - 10 into f(n) , that is
f(- 10) = - 7(- 10) + 4 = 70 + 4 = 74
Hello there!
We are given a function below:
[tex] \displaystyle \large{f(n) = - 7n + 4}[/tex]
To find f(-10), substitute n = -10.
[tex] \displaystyle \large{f( - 10) = - 7( - 10) + 4}[/tex]
Evaluate the f(-10)
[tex] \displaystyle \large{f( - 10) = 70 + 4}[/tex]
Recall
Negative × Negative = PositiveTherefore,
[tex] \displaystyle \large{f( - 10) = 74}[/tex]
f(-10) = 74
