It would be 50
130+180= 310
360-310= 50
You get 180 from the missing side by 70 that becomes 180.
Answer:
a = 3
Step-by-step explanation:
Factor both expressions
x² - x - 6
Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (- 1)
The factors are - 3 and + 2 , since
- 3 × 2 = - 6 and - 3 + 2 = - 1 , thus
x² - x - 6 = (x - 3)(x + 2)
-----------------------------------
x² + 3x - 18
consider factors of constant term (- 18) which sum to give the coefficient of the x- term (+ 3)
The factors are + 6 and - 3 , since
6 × - 3 = - 18 and 6 - 3 = + 3 , thus
x² + 3x - 18 = (x + 6)(x - 3)
Both expressions have a common factor of (x - 3)
Compare with (x - a ), then a = 3
Mg required per pound = 249/153 = 1.63mg
Therefore medicine required= 102 *1.63= 166.26g
Given:
The function is

To find:
The value of f(-1).
Solution:
We have,

Putting x=-1, we get




Therefore, the value of f(-1) is -12.
Y² = 12
y = 2√3
x = √6
Now, 4 /xy
= 4/2√3√6
= 2 / 3√2
= √2/3
In short, Your Answer would be √2 / 3
Hope this helps!
