QUADRATIC FORMULA
X = ?

x=5

Step-by-step explanation:

well first 2(2x-5) turns to 4x-10  because of distributive prperty

then simplify the other side 3x+x-2x to 4x-2x to 2x

then subtract 4x from both sides and you get -10= -2x

after divied -2x/-2 and -10/-5

and get x=5

then plug in 5 into x to make sure both sides are equal

and they equal 10=10

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
