So hmm notice the first picture, that's the "inscribed angle theorem", as you'd know
now, notice angle 2 in yours on the second picture
Answer:
-1
Step-by-step explanation:
equation:
3(5-4)-4(5-4)
3*5-3*4 -4*5-4*-4
15-12-20+16
3-4
-1
Answer:
<h2>(n-2)(2n² - a)</h2>
Step-by-step explanation:
Given the expression 2n²(n-2) - a(n-2), to write this expression in a complete factor form, simply follow the instruction;
Let's assume the original expression has been broken down into that form in question, if we look at both terms, we will see that n-2 in parenthesis is common to both terms, we can therefore factor out n-2 from both terms as shown;
= 2n²(n-2) - a(n-2)
= n-2(2n² - a)
Hence the complete factor form of the expression is (n-2)(2n² - a) because the expression cannot be simplified any further.
