Answer:
HCF Of two nos. is 17
Let another no. be x
we know that HCF ×LCM = Product of two numbers
17×140=20×(x)
20x=2380
x =2380/20
x=119
The other no. is 119
Answer:
First option
Step-by-step explanation:
The inequality says greater than or equal to 5. Which means n is greater than or equal to (≥) 5.
It's not the second option because less than or equal to means that n is less than or equal 5, which doesn't check out since 5 is the smallest value of n.
It's not the third option since it says that 5 is greater than n, when we know that one of n's values is 5.
It's not the fourth option since it says that that n is greater than 5, when we know again that one of the values of n is 5.
Your answer is the first option "n ≥ 5."
Hope this helps.

Answer: Choice A</h3>
Explanation:
For regular tessellations, the types of polygons that we can use are
- squares or rectangles
- equilateral triangles
- regular hexagons
We can only pick one of those shapes.
Shapes like regular octagons or pentagons will not work on their own because there is gap or overlap if we tried to glue them together. Think of tiles on the floor. There cannot be any gap or overlap when forming a tessellation.
If you wanted to use octagons to tessellate the plane, then you'd need squares to fill in the gaps. At this point, it's not considered a regular tessellation.
Answer:
Step-by-step explanation:
<u>Find the value of x:</u>
- P(triangle) = P(square)
- 3(x + 4) = 4(x + 2)
- 3x + 12 = 4x + 8
- 4x - 3x = 12 - 8
- x = 4
<u>Find the value of a:</u>
- P(hexagon) = 12x
- 6(1/2a + 1/2) = 12*4
- 3a + 3 = 48
- 3a = 45
- a = 15
Assumed b is the side of the rectangle (it is not indicated on the picture)
<u>Find the value of b:</u>
- A(rectangle) = A(square)
- (x + 2)² = b(a - 6)
- (4 + 2)² = b(15 - 6)
- 36 = 9b
- b = 4
