Step-by-step explanation:
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:
The order of operation will be reversed
Step-by-step explanation:
In order to solve two-step equations, we need to work backward with regard to the order of operations.
We would perform the addition & subtraction before multiplication & division.
1. Add or subtract to isolate the variable term.
2. Multiply or divide to solve for the variable.
3. Check your solutions.
Check the picture below.
notice that the inscribed angle at C is intercepting the arcEAB, and since we know that the arcAB is 72°, then arcEA is arcEAB - arcAB, or 102 - 72.
