I need help on this one. it says solve for w. and it says w-8=32. will someone help plz thx.

w= -4

Step-by-step explanation:

First we know 8 x 4 is 32 so then we make the 8 negative

and divide -8 by 32 which is -4

You can check it by doing -4 x -8 which is 32!

Remember-

1. When you multiply two negatives it equals a positive.

2. You can check by plugging -4 where w is  then solving.

3. If there is a subtraction next to a number  (w-8) then whichever number the subtraction sign is in front of is negative.

4. If a variable is next to a number it means to multiply the variable  by the number.

i dony know

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
