Answer:
4 divided by one-sixth = 2
Step-by-step explanation:
Given 4fraction bars
If each fraction bars has 6boxes, then we can get the total boxes for 4fractiom bars as shown;
1 fraction bars = 6boxes
4fraction bars = x
Cross multiply
1 × x = 4×6
x = 4× 6/1
x = 4 ÷ 1/6
Hence the division problem that modelled the expression is 4 ÷ 1/6
4÷1/6 = 4×6/1
4÷1/6 = 24
Option A is correct
Answer:
Option D is correct.
The equation with roots 3 plus or minus square root 2 is x² - 6x + 7
Step-by-step explanation:
The roots of the unknown equation are
3 ± √2, that is, (3 + √2) and (3 - √2)
The equation can then be reconstructed by writing these roots as the solutions of the quadratic equation
x = (3 + √2) or x = (3 - √2)
The equation is this
[x - (3 + √2)] × [x - (3 - √2)]
(x - 3 - √2) × (x - 3 + √2)
x(x - 3 + √2) - 3(x - 3 + √2) - √2(x - 3 + √2)
= x² - 3x + x√2 - 3x + 9 - 3√2 - x√2 + 3√2 - 2
Collecting like terms
= x² - 3x - 3x + x√2 - x√2 - 3√2 + 3√2 + 9 - 2
= x² - 6x + 7
Hope this Helps!!!
Since

is negative, it doesn't have any real roots.

All you have to do is multiply numerators by numerators and denominators by denominators. Simplify if needed
