Answer:
yeahh write explicit formula
Step-by-step explanation:
â¹=1 and 567+×an-¹+5
<em>A. 140°C</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<u><em>the correct form of the formula is</em></u>
<em>C = 5 (F – 32)/9</em>
<em>= 5(284 - 32)/9</em>
<em>= 5×252/9</em>
<em>= 1260/9</em>
<em>= 140° C</em>
<em>Good luck ! </em>
Let's call the width . Since the length is three more than the width, it is .
The area (which we know to be 70) is given by the multiplication of width and length:
To solve this equation, you can use the usual quadratic formula: given an equation , the two solutions are
which in your case becomes
So, two solutions are
Since we can't accept a negative length, we only accept the second solution.
So, the dimensions are 7 and 10
