Answer: Your answer is 12
Step-by-step explanation:
120/(6+4)=X
120/10=X
120/10=12
12=X
It’s just 5 you divide 9 into 45 and get a whole number of 5
The answer is 51.3 degrees because you add 90+38.7=128.7
then you do 180-128.7 because this is a linear/ supplementary triangle which adds up to 180
and you get 51.3 degrees
Factor the denominator
x^2+3x-10
(x+5)(x-2)
(x-2)/((x+5)(x-2))
The x-2 in the numerator and denominator cancel out.
Final answer: x+5
