Answer:
-48
Step-by-step explanation:
−112÷2 1/3 needs to be rewritten as -112 / (7/3), where 7/3 is the improper fraction version of 2 1/3.
Then we have
-112
---------
7/3
Recall that division by a fraction is equivalent to multiplication by the reciprocal of the fraction; thus, the above expression becomes
-112 * 3
-----------
7
This, in turn, can be reduced through division to -16*3, which equals -48.

Answer:
Given,
Now,
Use the algebraic identity ⇻ (a - b)² = a² - 2ab + b²
✐ So, the value of 9x² + 4y² - 1 is <u>24 + 12xy</u>
Now,
xy = - 2
So, 12xy = 12 × - 2 =<u> - 24</u>
•°• 24 + 12xy
= 24 + (-24)
= 24 - 24
= <u>0</u>
<h3>
⎆ The value of 9x² + 4y² - 1 is
<u>0</u>.</h3>
