Yes, because 2x2 equals 4 and 4/2 equal 2
2x2 = 4 , Four . 2x2 = 4 , Four .
What is the solution set of 2x2 + x = 15
If: 2x2 = 4 Then: x = the square root of 2
Mathematicians have proven that there are some equations that show that 2x2 does indeed equal 5, and 4
2x2 equals 5
no
Yes, because 2x2 equals 4 and 4/2 equal 2
"Equals" means "the same as." eg 4 = 2x2; four is the same as 2x2. eg "I am your intellectual equal"; our intellects are the same.

2x2 = 4 , Four . 2x2 = 4 , Four .
I'm sorry but I can't solve that problem. B(
What is the solution set of 2x2 + x = 15
If: 2x2 = 4 Then: x = the square root of 2
8 - 2x2 = x + 22 - 7Combine like terms on the right side:8 - 2x2 = x + 15Subtract 8 from each side:-2x2 = x + 7Add 2x2 to each side:0 = 2x2 + x + 7
4 equals 2x2, 6 equals 2x3
2x2 - 3 = 13 So 2x2 = 16 x2 = 8 So that x = ±2√2
