Answer:
For example, 6(1001) + 3(110) = 6006 + 330 = 6336 is a palindrome. Since 11 is a factor of both 1001 and 110, we conclude that all four digit palindromes are divisible by 11.

(9,3)
Step-by-step explanation:
Answer:
h = 3 cm
Step-by-step explanation:
Given that,
Diameter, d = 6 cm
Radius, r = 3 cm
Volume of the cone, V = 28.26 cm³
The formula for the volume of a cone is given by :
So, the height of the cone is equal to 3 cm.
Answer:
x = 5 (check the diagram included)
Step-by-step explanation:
The question is incomplete, I have included a diagram to aid the understanding of the question
Parallelograms are quadrilaterals which have their opposite sides parallel and equal. This also means that the opposite angles in a parallelogram are equal
From the attached figure, we have:
|FG| = 3x + 10, |HE| = 7x - 30
To calculate for the value of x that makes the quadrilateral a parallelogram, we have:
Remember the opposite sides of a parallelogram are equal
3x + 10 = 7x - 30
3x - 7x = 10 - 30
-4x = -20
x = 20 ÷ 4
x = <u>5</u>
x = 5 makes the quadrilateral a parallelogram
Suppose that the number u were thinking about is x thus :
Multiply both sides by 4
Divide both sides by 3
