Okay. 10×5=50cm^2 is the area of the rectangle
The height of the triangle is (18-10)=8cm
So (8×5)÷2=20cm^2
50+20=70cm^2 is the area of the composite shape
2,400 / 80
Just take 24÷eight and then add the two zeros at the end
Answer:
123
Step-by-step explanation:
Answer: It has two distinct real zeros.
Step-by-step explanation:
The formula that is used to calculate the discriminant of a Quadratic function is the one shown below:

In this case you have the following Quadractic function provided in the exercise:

Let's make it equal to 0:

You can identify that:

Knowing these values, you can substitute them into the formula and then evaluate:

Therefore, since:

You can determine that the it has two distinct real roots.
