Answer:
72 cm²
Step-by-step explanation:
The diagonal of the square divides the square into 2 right triangles.
let the legs of the triangle be x , then using Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
The hypotenuse of the triangle is the diagonal, thus
x² + x² = 12²
2x² = 144 ( divide both sides by 2 )
x² = 72 ( take the square root of both sides )
x = 
The area of the square = x² = ( )² = 72 cm²
Answer:
Luis wrote an incorrect expression.
Step-by-step explanation:
As per Terrell, the correct expression is (2x+2x) + (5x+5x) + (1+1) which is equal to 12x + 2
For you who got incorrect answer, the answer if you simplified it must be 12x + 2. Let's check:
Anya 2x+2x+5x+1+5x+1 =
12x + 2 [CORRECT]
Katrin 2(5x+1) + 2x
10x+2+2x
12x + 2 [CORRECT]
Luis 2(2x) + 2(5x+1)
4x+10x+2
14x + 2 [INCORRECT]
Steve 1+1+ x(2+2+5+5)
2+ x(12)
12x + 2 [CORRECT]
Answer:
2 2/5
Step-by-step explanation:
The answer would be 25...
Think about it, switch 25 with z
Answer 25 - 3 = 22
Correct
$30 is your constant
Months would be your independent variable
Total cost would be dependent
Therefore, your total cost would “depend” on the number of months “independent” times your constant of 30
