1 3/8 + 2 2/5 PLEASE HELP!!!

23/8

Step-by-step explanation:

first you want to make the 2 2/5 a complete fraction

To do this multiply the whole two by 5 then add your numerater

same with the 1 3/8 as above

by now you should have 11/8+12/5

now find a common denominater

at this point it should be 55/40+60/40

Then add them which will give you 115/40

lastly simplify and you will get 23/8

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
