<h3>
Answer: True</h3>
The key word here is "may" meaning that we could easily have 3 rational roots as well. An example of a cubic having 3 irrational roots would be
(x-1)(x-2)(x-3) = x³ - 6x² + 11x - 6
This has the rational roots x = 1, x = 2, x = 3.
However, we could easily replace 1,2,3 with any irrational numbers we want. So that's why the statement "a cubic has three irrational roots" is sometimes true.
In some cases, a cubic may only have 1 real root and the other 2 roots are imaginary.
The perimeter of frame is 1.29 greater
Step-by-step explanation:
Perimeter of a rectangular shape object is given by the formula;
2(l+w) when, l is length and w is width
Perimeter of the photo is;
2(8+6)= 2(14) =28 inches
Perimeter of the frame is;
2(10+8)= 2(18) =36 inches
Divide perimeter of frame by that of photo as;
36/28 =1.29
The perimeter of frame is 1.29 greater

Answer-
y = -1x or y = -x
Explanation-
Step 1: Look for a pattern in the x column and the y column.
X = -1, 3, 7, 11
(The pattern is that you add 4 with every number)
Y= 0, -4, -8, -12
(The pattern is that you subtract 4 with every number)
Step 2: Create and (if needed) simplify the slope
Slope = y/x
Slope -> -4/4
Simplified Slope -> -1
Step 3: Put it in slope-intercept form
Slope-intercept form -> y = mx + b
y = -1x + 0 -> y = -1x or y = -x
Answer:
Write down the numbers, one under the other, with the decimal points lined up
Put in zeros so the numbers have the same length
Then add using column addition, remembering to put the decimal point in the answer
