Multiple the sum of a number and 3 by the difference of 8 and the number

Mathematics
1 answer:
Whitepunk [10]3 years ago
6 0

Answer:

-n^2 - 5n + 24

Step-by-step explanation:

Let the number be n.

Then the sum of that number and 3 is n+3.

The difference of 8 and the number is 8 - n.

Then we get the expression (n + 3)(8 - n).

Performing the indicated multiplication, we get:

8n - n^2 + 24 - 3n, or

-n^2 - 5n + 24

Nothing more can be done, as this is not an equation, but rather an expression.

The number of cubic feet of water in a curved container can be approximated by v = 0.95h2.9. use a calculator to find the amount
Sati [7]
The first thing we must do for this case is to rewrite the expression of the volume correctly.
 We have then:
 v = 0.95 * h ^ 2.9
 Substituting the value of h we have:
 v = 0.95 * (7.5) ^ 2.9
 v = 327.6432831
 round to the nearest tenth:
 v = 327.6 feet ^ 3
 Answer:
 
the amount of water in the container when h = 7.5 feet is:
 
v = 327.6 feet ^ 3

von has a rectangular workroom with a perimeter of 26 feet. the length of the workroom is 6 feet. what is the width of vons work
daser333 [38]
Should be 7 feet. 6+6=12 then 26-12=14, divide that by 2 (for the other two sides of the rectangle), you'll get 7 ft.
