Step-by-step explanation:
x2 + bx +5 = 0,
where a,b and c are rational numbers.
Also it is given that the quadratic has 2 distinct zeros and one of it's zero is irrational.
We know that if it has a one irrational zero, the conjugated couple of the one zero is also a null with the same polynomial balance for a polynomial equation with rational coefficients." Therefore, in this case it is a quadratic equation, one is null and irrational; thus, the other zero is irrational.
Answer:
5z
Step-by-step explanation:
3z+5z-3z(3z gets cancelled)
5z
Answer:
2
Step-by-step explanation:
4x minus 4x then it leaves you with just 2 because the 4s cancel out
Answer:
360
Step-by-step explanation:
I got it right
6 x 7 + 9 x 7
Explanation:
Ok so if you separate that figure into two shapes, you will have 2 rectangle.
Its kinds too long to explain, but just know that to find the formula of a rectangle is length x width.
So, find the area of the rectangle on the left first:
The width of the rectangle on the left is 6
The length is 7
Multiply 6 x 7
Next, find the area of th rectangle on the right:
The length is 9
The width is 7
Multiply 9 x 7
Since this is originally one figure, we do this:
6 x 7 + 9 x 7
