Answer:
sqrt(144) = ±12
Step-by-step explanation:
sqrt(144)
What number, when multiplied by itself, gives 144
12*12 = 144
-12*-12 = 144
sqrt(144) = ±12

Answer:
Imara's error will be that she did not find the side lengths of the square with an area of 625.
Step-by-step explanation:
Imara used these steps to find the length of the hypotenuse of the right triangle.
Step 1: Find the area of the square with side lengths of 20 i.e. 400
Step 2: Find the area of the square with side lengths of 15 i.e. 225
Step 3: Find the sum of the areas of the two squares i.e. 625
Step 4: State the length of the hypotenuse i.e. 625
Therefore, Imara's error will be that she did not find the side lengths of the square with an area of 625. (Answer)
Answer: p = 8, -10
Step-by-step explanation: Solve for p by simplifying both sides of the equation, then isolating the variable.
