Complete question is;
An architect plans to build an extension to meiling's rectangular deck. Let x represent the increase, in meters, of her deck's length. The expression 4(x+8) represents the area of the deck, where 4 is the width, in meters, and (x+8) represents the extended length, in meters. Use distributive property to write an expression that represents the total area of meilings new deck.
Answer:
4x + 32
Step-by-step explanation:
We are told that the expression 4(x+8) represents the area of the deck.
Also, that 4 is the width, in meters, and (x+8) represents the extended length, in meters.
Thus, area is;
A = 4(x+8)
Using distributive property simply means we will distribute the term outside the bracket to each term inside the bracket.
Thus;
A = (4 * x) + (4 × 8)
A = 4x + 32
If we want to find the distance between two points on a number line use the distance formula:
Answer:
4/13 hours
Step-by-step explanation:
Total pounds of lasagna = 4 1/3 pounds
Total time taken to cook = 1 1/3 hours
How many hours per pound did it take to cook the lasagna?
Hours per pound of lasagna = Total time taken to cook / Total pounds of lasagna
= 1 1/3 hours ÷ 4 1/3 pounds
= 4/3 ÷ 13/3
= 4/3 × 3/13
= 4/13 hours
It will take 4/13 hours to cook each pound of the lasagna
Answer:
The derivative of any constant number is 0.
So,
Differentiating with respect to "x",
d f(x)/dx
=d 25/dx
=0
