A trinomial is a polynomial with three terms. It can be determined if it is a difference of two squares when you factor it.
The resulting factor of a trinomial that is a difference of two squares is: a²<span> – b</span>²<span> = (a + b)(a – b) or (a – b)(a + b)</span>
You will notice that the middle term is missing. This means that the middle term zeroes out as a result of having the same number of different signs (+ and -)
The cofunction identities for tangent are:
tan (90° – θ) = cot θ and cot (90° – θ) = tan θ
Answer:
..........................................................the answer is 12.5
Using pemdas you can solve it. Pemdas stands for parentheses, exponents, multiply, divide, add, and subtract. So you look at the problem and you look if there’s any parentheses which is not so then you move onto exponents which there is. Two to the third power is equal to 8. The problem then becomes 28+87/3•8
Then you look for multiplication. 3•8=24
It’s now 28+87/24
Next is division so you do 87/24 = 3.6
Now it is 28+3.6=31.6
The answer is 31.6
