Given:
a square with an area of a² is enlarged to a square with an area of 25a².
The side length of the smaller square was changed when The side length was multiplied by 5.
Area = (1a)² = a²
Area = 1a * 5 = 5a ⇒ (5a)² = 25a²
Convert the mixed numbers to improper fractions, then find the LCD and combine.
Exact Form:
7/3
Decimal Form:
2.¯3
Mixed Number Form:
2/1/3
I will say 36 but I also will say wait on someone else to answer
Answer:

Step-by-step explanation:
Hi there!
<u>What we need to know:</u>
- Linear equations are typically organized in slope-intercept form:
where m is the slope and b is the y-intercept (the value of y when x is 0) - Perpendicular lines always have slopes that are negative reciprocals (ex. 3 and -1/3, 5/6 and -6/5, etc.)
<u>1) Determine the slope (m)</u>
y=x-9
Rewrite the equation
y=1x-9
Now, we can identify clearly that the slope of the line is 1. The negative reciprocal of 1 is -1, so therefore, the slope of a perpendicular line would be -1. Plug this into
:

<u />
<u>2) Determine the y-intercept (b)</u>

Plug in the given point (7,9) and solve for b

Add 7 to both sides to isolate b

Therefore, the y-intercept is 16. Plug this back into
:

I hope this helps!
