Answer:
-13/8
Step-by-step explanation:
u divied by -8 to get n by itself
Answer:
see below
Step-by-step explanation:
(3x + 8) units by (6x + 5) units.
A = l*w
= (3x+8)(6x+5)
Distribute
3x*(6x+5) + 8(6x+5)
18x^2 +15x + 48x +40
Combine terms
18x^2+63x+40 units^2
The degree is 2 ( the highest power of x)
This is a trinomial ( it has 3 terms)
Multiplication is closed for polynomial multiplication
We started with polynomials and we ended up with a polynomial.

Answer:
Step 4
Step-by-step explanation:
Given: Steps used by Shelly to evaluate the expression
To find: step that includes Shelly's mistake
Solution:
According to PEMDAS,
P denotes Parentheses
E denotes Exponents
M denotes Multiplication
D denotes Division
A denotes Addition
S denotes subtraction
Step 3 is and step 4 is
In step 4, first subtraction operation has been applied before the division operation.
There is a mistake in step 4 as according to PEMDAS, first -20 should be divided by 5 then 1 should be subtracted from the resultant number.
Answer:
406.153846 or about 406 feet per minute
Step-by-step explanation:
Start by converting the 13 minutes per mile to feet per minute by turning the mile into 5,280 feet. So you run 5,280 feet in 13 minutes. Then you divide 5,280 by 13 so you get the amount of feet per minute, hence about 406 feet per minute.
I didn't know if you needed an exact answer or to round so I gave you both :)
