Answer:
The student is correct.
Step-by-step explanation:
Given that 5x² = 20:
It is true that the value of x = 2 because 2² = 4, and when you multiply 4 with 5, you'll get a product of 20:
5x² = 20
5(2)² = 20
5(4) = 20
20 = 20
Therefore, the student is correct that x = 2.

Answer:
B. 24 units
B. (-2 , -1)
D . A(-5, 3), B(-2 , 3), C(3, -3), D(-7, 3)
Step-by-step explanation:
AC = 8, AB = 6
BC = √(8^2 + 6^2)
BC = √100
BC = 10
Perimeter = 10 + 8 + 6 = 24 units
