Answer:
-13a^2 + 170ab - 13b^2.
Step-by-step explanation:
1. 36(a+b)^2 - 49(a-b)^2
This is the difference of 2 squares: a^2 - b^2 = (a + b)(a - b).
36(a+b)^2 - 49(a-b)^2
= (6(a + b) + 7(a - b))( 6(a + b) - 7(a - b))
= (6a + 7a + 6b - 7b)( 6a - 7a + 6b + 7b)
= (13a - b)(-a + 13b)
If you require the expansion of this it is:
-13a^2 + 170ab - 13b^2.
Answer:
14 pints
Step-by-step explanation:
hope it helps a lit ur welcome ,,please follow
1) Write 3% as 3/100
2) Since, finding the fraction of a number is same as multiplying the fraction with the number, we have:
of 2500 = × 2500
Therefore, the answer is 75
If you are using a calculator, simply enter 3÷100×2500 which will give you 75 as the answer.
Commission = $75
D = S × T
S = D ÷ T
T =D ÷S
sorry thats all i can do
