Even, Odd, or None? -6x² + 8x4 + 3x6 - 6

1 answer:

4 0

2 would be the answer if you follow your order of operations the order of operations is parentheses exponents multiply divide whichever comes first and add and subtract whichever comes first and -6x with the exponent of 2 it can be turned into -36 cuz you're multiplying six two times then 8 * 4 is 32 and 3 * 6 is 18 so you would do -36 + 32 which would give you negative 4 then you're going to bring down the 18 then do -4 + 18 which would give you 4 then you're going to bring down the - 6 and do 4-6 and -6 -4 gives you positive 2

Adriano wants to get a new cell phone plan. Company A: $80 for a new phone in the monthly fee of $45 a month. Company B: she can

Degger [83]

Answer: it will take 2 months.

Step-by-step explanation:

Let x represent the number of months it will take for the total cost for both companies to be equal.

Company A: $80 for a new phone and the monthly fee of $45 a month. This means that the total amount that Company A charges for x months would be

80 + 45x

Company B: she can keep her all sound and pay $85 a month. This means that the total amount that Company B charges for x months would be

85x

For the total cost for both companies to be equal, the number of months would be

80 + 45x = 85x

85x - 45x = 80

40x = 80

x = 80/40 = 2

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 18 N acts on

inysia [295]

Answer: $F=15N$

Step-by-step explanation:

1. You know that the force acting on the object varies directly with the object's acceleration. Then, by definition, you have:

$F=ka$

Where $F$ is the force acting on the object, $a$ is the object's acceleration and $k$ is the constant of proportionality.

2. Keeping this on mind, you can calculate the constant of proportionality by substituting $F=18$ and $a=6$ into the equation and solving for $k$ :

$18=k6\\k=\frac{18}{6}\\k=3$

3. Now, you can calculate the force when the acceleration of the object becomes 5 m/s², as following:

$F=3(5)\\F=15$

3. The result is:

$F=15N$

The sides of this rectangle are

Naddik [55]

The longer side is at first 7cm and the shorter is 2cm.

So since 7cm(the longer side)×5=35cm then the shorter side(2cm) multiplied by 5 should give you the right answer.
