Answer:
0.21 square meter
Step-by-step explanation:
Area of the section of wall = 1 square meter
Dimension of part of mural completed = 
meter by 
meter
Part of the mural completed = Area of the rectangular part of mural completed
But,
Area of a rectangle = length x width
So that,
Part of the mural completed = length x width
= x
= 
= 0.2083
Part of the mural completed = 0.21 square meter
The part of the mural that has been completed by Beverly is 0.21 square meter.
Answer:
Step-by-step explanation:
We can use a system of equations in order to solve for both of the numbers. Let's start off by assigning variables to each number. The bigger number can be 'x', and the smaller number can be 'y'.
We can make two equations from the given:
x = 18 + y
("One number is 18 more than another number")
x + y = 36
("The sum of the numbers is 36")
If you look at the first equation, the variable 'x' already has a value (18 + y). We can input its value into the second equation in order to solve for y:
x + y = 36
(18 + y) + y = 36
18 + 2y = 36
2y = 18
y = 9
Input the value of 'y' into the first equation:
x = 18 + y
x = 18 + 9
x = 27
<u>One number is 27 and the other number number is 9.</u>

Answer:
(15c + 8)(a + b).
Step-by-step explanation:
15c·(a+b)+8·(b+a)
(a + b) is common to both parts:
= (15c + 8)(a + b).
