Answer:
a) A = 48x + 24
b) Yes
Step-by-step explanation:
a) The area of a rectangle is found using A = l*w. Substitute l = 6x + 3 and w = 8 to find the area.
A = (6x + 3)(8) = 48x + 24
b) Repeat the same process with the formula A = l*w. Substitute l = 4x + 2 and w = 12.
A = (4x+2)(12) = 48x + 24
The areas are the same.
Devide the numerator by the denominator, and look for the repeating numbers
17 divided by 60 = 0.283333333 = repeating
25 divided by 60 = 0.4166666667 = terminating at the 7
31 divided by 44 = 0.7045454545= repeating i think? sorry i cant remember if double numbers repeating like this is the same
54 divided by 72= 0.75 = terminating
Divide the expression for the area by the length 6x ( width = area/length)
this gives the width :-
= 2x^2 + 3x - 4 Answer

Number of rooms left excluding a quarter of 140 is: 105 rooms.
<h3>What is a Quarter of a Number?</h3>
A quarter is one-fourth. A quarter of a number is therefore, one-fourth of that number or 1/4 part of the number.
Therefore, number of rooms cleaned = 1/4(140) = 35.
A quarter of the 140 rooms is: 35.
Number of rooms left for cleaning in the afternoon = 140 - 35
Number of rooms left for cleaning in the afternoon = 105 rooms.
