Answer:
9/10
Step-by-step explanation:
you find the lowest common denominator in this case is 10
then you take 1/2 and multiply it by 5 both the bottom and top and then you should get 5/10
next you do the same with 2/5 but this time to the get the denominator to 10 you multiply by 2 again multiply both bottom and top and you should get 4/10
now you just add 4/10 and 5/10 together and you get 9/10 or 0.9 as a decimal
Question

It's C
Step-by-step explanation:
Simplify the expression
Answer:
4x²+13x+9
iwill give you good method to simplify this
firstable take the 4 from x² and multiply it by 9
x²+13x+36
we find this equation
so the values is 4 and 9 because 4+9=13
4×9=36
(x+ )×(x+ )
first we take 9 and devide it by 4
9/4 the four for the x and the nine is number
so its will be
(4x+9)×(x+ )
same thing with 4 devide by 4 so the value is 1
so its will be like this
(4x+9)×(x+1) and this is the answer hopefully you understand my explain with my English
