Answer:

a. x is equal to 54.5

Step-by-step explanation:

The interior angles of a pentagon will add up to 540. Since it is a regular pentagon, each angle would be 108 degrees. So we can set the value of the angle to 108 and solve for x.

2x - 1 = 108

2x = 109

x = 54.5

Which number can each term of the equation be multiplied by to eliminate the decimals before solving? -m+0.02+2.1m=-1.45-4.81m
Andrews [41]
The number that each term of the equation be multiplied by to eliminate the decimals before solving -m+0.02+2.1m=-1.45-4.81m

It would be better to group all similar numbers.
<span>-m+0.02+2.1m=-1.45-4.81m
</span>-m + 2.1m + 4.81m = -1.45 - 0.02
5.91m = -1.47

The equation shown above, in order for us to eliminate the decimal, 
we need to divide 5.91.

Given the function: f(x) = 2x3 - 3/2x, find f(-4).
Sergeu [11.5K]

Answer:

D) -122

Step-by-step explanation:

Given:

f(x) = 2x^3-\frac{3}2x

We need to find f(-4).

Now by substituting the value of x =-4 in above equation we get;

f(-4)= 2\times(-4)^3-\frac{3}{2}\times(-4)\\

By using PEDMAS we will solve for exponential function first we get;

Now we know that (-4)^3=-64

So we get;

f(-4)= 2\times(-64)-\frac{3}{2}\times(-4)\\

Now using PEDMAS we will solve division.

f(-4)= 2\times(-64)-1.5\times(-4)

Now using PEDMAS we solve multiplication.

f(-4)= -128+6

Finally by subtraction we get;

f(-4)= -122
