If A = 3 and B = -1/2 solve the following equations. 1. A(B)

2. 2B−A

3. 4A + B Mixed numbers must be made improper fractions or decimals

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.

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

51840000 cm 2

step-by-step explanation:

the answer is 5/14.

hope this .
