A fenced in rectangular region with the dimensions 4 yards by 8 yards is suddenly expanded by the same distance in each dimensio
Korolek [52]

Answer:

The distance added to each dimension is 2 yards.

Step-by-step explanation:

The initial dimensions of the rectangular fence is 8 yards by 4 yards.

The initial area of the rectangular fence = area of a rectangle

area of a rectangle = length x width

So that,

The initial area of the fence = 8 x 4

                                              = 32

The initial area of the fence is 32 square yards.

But, with the new dimensions, area = 60 square yards.

(4 + x) x (8 + x) = 60

x^{2} + 12x + 28 = 60

x^{2} + 12x - 32 = 0

(x + 14) = 0 or (x - 2) = 0

x = -14 or x =2

Thus, x = 2

The distance added to each dimension is 2 yards.

Sam baby-sat for x hours and earned $75. If he baby-sits for y more hours at the same rate, his total earnings will be $100. Whi
77julia77 [94]

The situation can be modeled with the linear equation:

$75 + y*($75/x) = $100

<h3>Which of the following equations represents this situation? </h3>

We know that if she wors for x hours, she earns $75.

This means that the amount that she gets per hour is:

R = $75/x.

Now, if she works y more hours, then she gets another $25 (for a total of $100).

We can write this as a linear equation:

y*($75/x) = $25

We can rewrite this as:

$75 + y*($75/x) = $100

So the correct option is B.
