You know that the sides of a square are increased by 2 inches: the expression should be written as (x+2)
The area is 25 square inches
The area of a square is s×s or s²
so it can be solved as:
(x+2)²=25
![(\sqrt{x+2})^{2} =\sqrt{25}](https://tex.z-dn.net/?f=%28%5Csqrt%7Bx%2B2%7D%29%5E%7B2%7D%20%20%3D%5Csqrt%7B25%7D)
x+2=5
x=3
<u>The length of the original side is 3 inches</u>
Hope it helps!
Answer:
Option D.
Step-by-step explanation:
First, let's do a little review of this excersice. Of the first 150 participants, 36 chose the first picture, and of the other 150 participants, p chose the first picture in the set.
Hence, the proportion of the participants who chose the first picture in the set is 36 300 p. Since more than 20% of all the participants chose the first picture, it follows that 36 0.20 300 !p . This inequality can be rewritten as p + 36 > 0.20(300). Since p is a number of people among the remaining 150 participants, p ≤ 150.
Choices A, B, and C are incorrect and may be the result of some incorrect interpretations of the given information or of computational errors.

Answer:
No
Step-by-step explanation:
-2/5 is not equal to 2/5 because it is negative and 2/5 is positive. This actually means that -2/5 is the opposite of 2/5.
