Flashcards
√9
√9
The square root of 9 is 3, because 3 multiplied by itself equals 9.
2x+5=2+3x
2x+5=2+3x
To solve for x, you need to isolate it on one side of the equation. Subtract 2x from both sides, and then subtract 2 from both sides. This leaves you with x = 3.
4×5:(5+4)=2,(3)
4×5:(5+4)=2,(3)
The equation is false. 4 x 5 equals 20, and 5+4 equals 9. 20 divided by 9 does not equal 2 (or 3).
