Answer: 9 or 10
Step-by-step explanation:
That is an isloated triangle.
30+[ ]+[ ]= 180 degrees.
Reminder: [ ] & [ ] is a same amount of number.
So 11*x-18 is [ ].
180-30= [ ] & [ ].
[ ] & [ ]= 150.
Then, [ ] is 150/2.
[ ]= 75.
<u>(11*x - 18)= 75 degrees.</u>
9*9-18= Answer.
I hope that helps :D
Answer:
x = -16
Step-by-step explanation:
-2(x +14)+1=5
solution
-2x - 28 + 1=5
-2x - 27 = 5
now, move the x value from left to right and constant move from right to left to solve for further
-5 - 27 = 2x
-32 = 2x
-32/2 = x
-16 = x
hence answer is x = -16
Answer:
According to factor theorem, if f(x) is a polynomial of degree n ≥ 1 and 'a' is any real number, then, (x-a) is a factor of f(x), if f(a)=0. ... Also, we can say, if (x-a) is a factor of polynomial f(x), then f(a) = 0. This proves the converse of the theorem.
