Original Question:
100 - [(25/5) x 10] = ?
Note: Always answer what's inside FIRST. In this case, the main ts the brackets, but there's also parenthesis in it too. So solve that.
→100 - [(5) x 10] = ?
Now, solve what's inside the brackets.
→100 - [50] = ?
Well, you can get rid of the brackets.
→100 - 50 = ?
Subtract!
→100 - 50 = 50
Solution:
50
Answer:
(D)(x-2)(x+2)
Step-by-step explanation:
As raízes do polinômio são 2 e -2, portanto sua forma fatorada tem que ser (x-x1)(x-x2) se x1=2 e x2=-2. Então:
p(x) = (x-2)(x+2)
First multiply all the brackets with the outside number
So 3(2x-4) and 2-(x+1)
=6x-12)= -2x-2+4
Move x to one side
6x-2x= 12-2+4
Solve
4x= 14
Divide by 4
X=7
Answer: 16.5%
Step-by-step explanation:
given data:
estimated circumfrence of the earth = 250,000 stadia.
Actual value = 46,620km
expected Value = 40,030.3km
solution:
percentage error = actual value – expected value/ expected value * 100
= 46,620 – 40,030.3 / 40,030.3 * 100
= 6589.7 / 40,030.3 * 100
= 0.16462 * 100
= 16.5%
percentage error is 16.5%
