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.

Answer:
her profit is $25
Step-by-step explanation:
Given that
She spends $15 for purchasing fabric so that she make the baby blankets
And, she can make 4 blankets from one piece of fabric
Now she sold the blankets for 10 each
So we need to find out the profit
As we know that
Profit = Selling cost - purchasing cost
= (4 × $10) - $15
= 40 - $$5
= $25
hence, her profit is $25
