It is: 49-28 = 21
7 squared is 49 and 5 squared is 25. So the difference is 49-25=24
78 - (-49) is the same as 78 + 49 which equals 127
79 + 49 = 128 79 - 49 = 30
The difference is 14 units. Dividing 14 by 49 gives you an increase of 28.5%.
49 − 28 = 21 difference 21 / 28 x 100 = 75%
It is a difference of squares. 9x^2-49=(3x+7)(3x-7)
the difference is that if you are on lets say a $49 CAP. it means that you will only pay $49 and you will get all the free calls and texts included. but if you are on a $49 PLAN that $49 is for "renting" the phone and you will have to top up your credit depending on how much you usually spend on calls if you where on a pre-paid thing.
x4-49 is the difference of two squares when factored as (x2-7)(x2+7)
49 ounces
The answer is 49 and the difference is 9... X + 9 = 41 41 - 9 = 32.
The difference between (5) squared and (7) squared can be calculated by first squaring each number. (5) squared is (25) (since (5 \times 5 = 25)), and (7) squared is (49) (since (7 \times 7 = 49)). The difference between these two results is (49 - 25 = 24). Thus, the difference between (5) squared and (7) squared is (24).
