Please help, im not sure if i quite get this.

hypotenuse=h

h = 1 + 1,5

h= 2,5

h²= catheto²+catheto²

2,5² = 1,5² + x²

x²= 2,5² - 1,5²

x²= 6,25 - 2,25

x²=4

now you have to do the square root of 4 which is 2 (2×2 = 4)

x= 2

correct answer:

a + bi

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
