Answer:
55x^4+25x^3+35x^2
Step-by-step explanation:
5x²(4x^2+8x-1 and 7x^2-3x+8)
Applying distribution property,we have
- 5x^2(4x^2+8x-1 + 7x^2-3x+8)
- (5x^2)*(4x^2)+(5x^2)*(8x)+(5x^2)*(-1)+(5x^2)(7x^2)+(5x^2)*(-3x)+(5x^2)*(8)
Simplifying them,we have
- 20x^4+40x^3−5x^2+35x4−15x^3+40x^2
- 55x^4+25x^3+35x^2
Given:
The square base pyramid with height 3 cm and base edge 2 cm.
To find:
The volume of the square pyramid.
Solution:
Volume of a square base pyramid is:
...(i)
Where, B is the base area and h is the height of the pyramid.
Base is a square with edge 2 cm, so the base area is:

Where, a is the edge of the square base.


Putting
in (i), we get
Therefore, the volume of the given pyramid is 4 cm³.
The cost price of the product will be 25000.
<h3>How to calculate the price?</h3>
From the information given, the cost price is 25000. The loss is 10%. This will be:
= 25000 - (10% × 25000)
= 25000 - 2500
= 22500
The tax is 13%. This will be:
= 22500 + (13% × 22500)
= 22500 + 2925
= 25425

Answer:
The value of x is 3
Step-by-step explanation:
The stage is rectangular in shape.
The formula for area of a rectangle is:
Length × Width
Length = 24 feet
Width = 4x + 4 feet
Hence:
384 = (4x + 4) × (24)
384 = 96x + 96
Collect like terms
384 - 96 = 96x
288 = 96x
x = 288/96
x = 3
The value of x is 3
A) Action: multiply both sides by 4.
Have a look:
(x/4)x4=16x4
x=64
As you can see, the value of x can be found by multiplying 4 on both sides.
Hope I helped :)
