Isamu decided to use blocking to deal with an extraneous factor in his experiment . What will blocking do to the subjects in his experiment ?

9 x 8 divided by (5-3)=36

7

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
