For A put 160 (division sign} 4.
For B put -40
The rate of change is -29/5x^2
NO. The mirror will not fit in a space that is 15 inches by 16 inches
<em><u>Solution:</u></em>
Given that area of mirror is 225 square inches

Converting the above mixed fraction we get,

Let us find the length of mirror
The area of mirror is given as:
area of mirror = length x width
Substituting the given values,

Thus length of mirror is 16.36 inches
<em><u>Will the mirror fit in a space that is 15 inches by 16 inches?</u></em>
NO. The mirror will not fit in a space that is 15 inches by 16 inches
Because length of mirror is 16.36 inches whereas the given space is 15 inches long
16.36 > 15 so the length of mirror will not fit inside the space
Also width of mirror is
inches which is less than the given space whose width is 16 inches
13.75 < 16 so the width of mirror will not fit inside the space

so you cross multiply 36*7 which is 252÷100= 2.52. Then add 2.52 to 36 and your answer is 38.52
