The first step in solving this problem is to compute for the
area of the rectangular wall. The formula in computing the area of a rectangle
is:
A = LW
Substituting the given measurements in the problem to the
formula:
A = 13 (12)
A = 156
Therefore, the area of the wall is 156 square feet. To compute
the wallpaper cost of the wall, you have to multiply the cost per square foot
to the total area.
$8 per square foot x 156 square feet = $1,248
Therefore, the wallpaper cost for the wall is $1,248
If it is 2.25 yards per dress, and 4.15 a yard, multiply 2.25 by 4.15 and you get 9.3375 or just 9.34. if there are 4 girls, multiply 9.34 by 4 and you get $39.76
If you are trying to find R, then it's 31/500, or 0.062.
To square a number, multiply the number by itself.
Answer:
Step-by-step explanation:
What you are doing is removing the brackets. That shows up as multiplying both terms inside the brackets by the factor outside the brackets (2).
This is a classic example of the distributive property.
