Step-by-step explanation:
length = width + 4
length×width = 77
using the first in the second equation
(width + 4)×width = 77
width² + 4width = 77
now, what square or squaring factors can create this ?
we are looking for (width + a)(width + b).
we know, this is
width² + (a+b)width + ab
so, what a, b can create 4 (the factor in our actual equation) ?
1, 3 and 2, 2, if we are only looking at whole numbers.
and which of the possibilities can we use to turn 77 into a square number ?
81 is only 4 away ...
2+2 = 4.
aha !
so, we can actually say our equation is
width² + 4width + 4 = 77 + 4
and then
(width + 2)² = 81
width + 2 = 9
width = 7 m
length = width + 4 = 7 + 4 = 11 m
<span>"Give an example of a sound financial decision Maura might make to support this goal. Why is it sound?"
<span>
</span>She could choose to carefully budget her trip and avoid overspending at all costs. This prevents going into debt. She should also save up extra money in the event of an emergency.
</span><span>Then give an example of a poor financial decision Maura might make considering her goal. Why is it a poor decision?</span><span>
Not having a plan would be a poor decision on her part. She could end up spending too much and not realize how much money she has left.
I hope I helped!

<em><u>Answer:</u></em>
s = $39,340
<em><u>Explanation:</u></em>
Note: I will use the symbol "n" instead of "t" in the solution.
<u>The given formula is:</u>
s = 32,512 * (1.1)ⁿ where "n" is the number of years.
We want to get the salary after 2 years. This means that we will substitute with n = 2 in the above equation and get the value of s.
<u>This is shown as follows:</u>
s = 32,512 * (1.1)²
s = $39,339.52 which is approximately $39,340
Hope this helps :)
Answer:
we need the other options to find out whats not equivalent to that problem.
We know that
the transformation
f(x)--------> f(x+2)
that means
A point (x,y) in graph of f(x)------> become a point (x-2, y) in graph of f(x+2)
hence
point (5,-8)-------------> become a point (5-2,-8)-----> (3,-8)
the answer is
the point (3,-8)
