The square root of 46 is 6.78
Answer:
The answer to your question is: x₁ = 9 ; x₂ = -2, third option
Step-by-step explanation:
The excluded values are those that make the denominator equal to zero.
To find the excluded values, just factor the denominator and equal to zero to find the roots.
Process
x² - 7x - 18
- Find to numbers that added gives -7 and multiply -18.
- These numbers are -9 and + 2, because
-9 + 2 = -7
and -9 x 2 = -18
(x - 9) (x + 2) = 0
x₁ - 9 = 0 x₂ + 2 = 0
x₁ = 9 x₂ = -2
Test
(9)² - 7(9) - 18 (-2)² - 7(-2) - 18
81 - 63 - 18 4 + 14 - 18
81 - 81 18 - 18
0 0
So the range of set A is 9.6
The range of set B is 5.6

Step-by-step explanation:
one cocoa pod makes 5/6 bar

42/5 = 8.4
He needs more than 8 pods per day, so he must harvest 9 pods per day.

7x·1x=7x

This equation can't be evaluated, but you could make up. an answer by yourself, this is just the other way of saying x7·x-5
