In the Pythagorean Theorem b is not twice a. The formula is [ a squared + b squared = c squared].
a + b = 2a - 8 ie - a = - b - 8; a - b = 2b - 4 ie a = 3b - 4 so b + 8 = 3b - 4, ie b = 6 and a = 14 Check: 14 + 6 = 28 - 8 yes; 14 - 6 = 12 - 4 yes!
2xa/b
Call the digits 'A' and 'B', so that the number is written: AB.10A + B = 4 (A+B)10A + B = 4A + 4B6A = 3B2A = B ---> any 2-digit number where the units digit is twice the tens digit12 or 24 or 36 or 48
b = 2a
2b
It is 2b (as Hamlet might have questioned!).
Twice the difference between a number and thirteen can be written as 2 (b - 13) Five more than twice the difference between a number and thirteen can be written as 2 (b - 13) + 5. The algebraic expression is 2 (b - 13) + 5.
It is 2b (as Hamlet might have questioned!).
A >= 2B (A is twice as many as B, or greater than twice of B)
Each number represents letters. For example, the number 2 represents letters A, B and C.If you wanted the letter B, for example, then you would press the number 2 twice.

The product of twice "a" and "b" can be expressed as: 2ab In this expression, "a" and "b" are variables that represent numerical values. Multiplying "a" and "b" gives their product, and then multiplying the result by 2 gives twice that product.
The measure of A is 60.
