Answer:
Lisa's percentage of error regarding the weight of the dog was 57.14%.
Step-by-step explanation:
Given that the German Shepard actually weighs 28 pounds, but Lisa thought the dog weighed 44 pounds, to determine what is the percent error the following calculation must be performed:
28 = 100
44 = X
(44 x 100) / 28 = X
4,400 / 28 = X
157.14 = X
157.14 - 100 = 57.14
Thus, Lisa's percentage of error regarding the weight of the dog was 57.14%.

Expand the second and 3rd factors first. Then worry about the x.
Solution
x(x + 2)(x + 4)
<em>first</em>: x * x = x^2
<em>Outside</em>: 4*x = 4x
<em>Inside</em>: 2*x = 2x
<em>Last:</em> 2*4 = 8
Combine
x^2 + 4x + 2x + 8
x^2 + 6x + 8
Now is the time to worry about the extra x
x(x^2 + 6x + 8)
remove the brackets.
x*x^2 + x*6x + 8*x
Combine
Answer: x^3 + 6x^2 + 8x
Answer:
64 slices
Step-by-step explanation:
The first step to solving this is to find out how many slices of bread there were in total. We know that each loaf of bread had 16 slices, and we know that there were 8 loaves. To get the amount of slices, we multiply the amount of slices in each loaf by the number of loaves there are.
16⋅8=128 slices of bread in total
Now that we know the total number of slices, we need to find how many sandwiches they made. If they used two slices per sandwich, we would divided the total number of bread slices by two.
128÷2=64.
