Okay i need to know first is this math or physics ? Cz everyone has a different solution
Step-by-step explanation:
To do Order of Operations, we need to go with the order of the formula, PEMDAS.
P= Parenthesis
E= Exponents
M= Multiply (Whatever Comes First in Equation: M and D)
D= Divide
A= Addition (Whatever Comes First in Equation: A and S)
S= Subtraction
---------------------------------------------
So, we need to start with parenthesis, there aren't any, so we move on to Exponents.
There are no Exponents either, so we start with division, then multiplication.
(We always have to go left to right).
So,
-9 - 6 + <u>8 / -4</u> x -2
-9 - 6 + <u>-2 x -2</u>
-9 - 6 + 4
Our problem is:
-9 - 6 + 4
We do subtraction, then addition. (Left to Right)
<u>-9 - 6 </u>+ 4
<u>-15 + 4</u>
-11.
Therefore, the answer is -11.

Answer:(2x+5)(x+5)=0
Step-by-step explanation:
2x^2+15x+25=0
Factorise we have
2x^2+10x+5x+25
(2x^2+10x)+(5x+25)=0
2x(x+5)+5(x+5)=0
(2x+5)(x+5)=0
Distribute 7 to both n and 1
7(n + 1) = 7n + 7
5n + 7 = 7n + 7 - 2n
Combine like terms
5n + 7 = 7n - 2n + 7
5n + 7 = 5n + 7
If you want to solve for n, subtract 7 from both sides
5n + 7 (-7) = 5n + 7 (-7)
5n = 5n
then divide 5 from both sides
5n/5 = 5n/5
n = n
Effectively, this equation is <em>unsolvable</em>
hope this helps
Queremos ver que fracción de la finca se ha destinado a plazas de aparcamiento.
La solución es:
La fracción de la finca que se destina a plaas de aparcamiento es 3/56
Sabemos que originalmente se iba a destinar 3/14 del total de la finca a plazas de aparcamiento, pero finalmente se destino 3/4 de lo previsto a zonas ajardinadas.
Es decir, <u>se destino 3/4 de los 3/14 del total de la finca</u> a zonas ajardinadas, entonces <u>el 1/4 restante se dedico a plazas de aparcamiento</u>, esto da:
(1/4)*3/14 = 3/56
La fracción de la finca que se destina a plaas de aparcamiento es 3/56
