Step-by-step explanation:
90% = 72 questions
\\Find 1%
1 % = 72 ÷ 90 = 0.8
\\Find 100%
100% = 0.8 x 100 = 80 questions
Answer: There were 80 questions
Answer:
x = 4
Step-by-step explanation:
Vertical angles are equal.
m∠1 = m∠2
10x - 9 = 4x + 15
Add 9 to both sides
10x = 4x + 15 + 9
10x = 4x + 24
Subtract 4x from both sides
10x -4x = 24
6x = 24
Divide both sides by 6
x = 24/6
x = 4
Just divided 1.3/100 and it gives you 0.013
The given polynomial is

As this is a fourth degree polynomial, we can not directly use any formula, So here we will use hit and trial method
check whether x=-1 is a zero of the polynomial or not

Hence x=-1 is not a zero.
Now check whether x=-2 is a zero of the polynomial or not

Hence x=-2 is a zero of the polynomial.
Hence we can re-write the polynomial as

Hence the required binomial is (x+2)
