7 0

Hi!

The number has a zero in the denominator.

If a number has a 0 in it's denominator, then it's not rational

Division by 0 is undefined.

Hope this helps you!

What are the solution(s) of the quadratic equation 98 – x2 = 0

DanielleElmas [232]

To solve first move the 98 to the other side by subtracting it from both sides. Then divide by - 1 on both sides to that the x^2 is no longer a negative. You are left with:

$x^{2} = 98$

Now square root both sides to get

$x = +/- \sqrt{98}$

The two factors that make up 98 are 49 and 2. 49 can be square rooted. So we are left with these answers:

$x = - 7 \sqrt{2}$ and $x = 7 \sqrt{2}$

You design the wooden picture frame and paint the front surface.

Hitman42 [59]

Answer:

a) 8x + 28
b) 68 in²

Step-by-step explanation:

Area of the frame with picture:

A = lw
A₁ = (x + 4)(x + 7) = x² + 11x + 28

Area of the picture:

A₂ = x(x + 3) = x² + 3x

Area of the wooden frame is the difference of the above values:

A₃ = A₁ - A₂
A₃ = x² + 11x + 28 - x² - 3x
= 8x + 28

When x = 5, the picture frame area is:

A₃ = 8*5 + 28 = 40 + 28 = 68 in²

Determine if the sequence is arithmetic write yes or no 5,9,14,20

makkiz [27]

Answer: No

Step-by-step explanation:

An arithmetic sequence is one where the same number is being added to the number before it. For example, 2, 4, 6, 8..., where 2 is being added to each number.

In this case, however, the number being added is not consistent with this pattern. Between 5 and 9, the difference is 4 and between 9 and 14, the difference is 5, and so forth. This pattern does not follow the rules of an arithemtic sequence.
