Answer:

x=20

Step-by-step explanation:

The line is a straight line, which is 180 degrees

x+100+3x = 180

Combine like terms

100+4x = 180

Subtract 100 from each side

100+4x-100=180-100

4x=80

Divide by 4

4x/4 = 80/4

x=20

Find the limit of the function by using direct substitution. limit as x approaches one of quantity x squared plus three x minus

ivann1987 [24]

<u>Answer:</u>

Limit = -1

<u>Step-by-step explanation:</u>

We are given the following function:

$x^2 + 3x -1$

We are to calculate the limit of this function as x approaches zero.

For that, we will use direct substitution method and substitute the x with 0 in the given function to calculate its limit as follows:

$x ^ 2 + 3 x - 1$

$( 0 ) ^ 2 + 3 ( 0 ) - 1 = - 1$

Therefore, the limit is -1.

Sebuah balok berukuran panjang 3 cm, lebar 4 cm, dan panjang diagonal ruang 13 cm. Volume balok adalah

kramer

Answer:

$V=144\ cm^3$

Step-by-step explanation:

#We use the base diagonal and the height diagonal to calculate the beam's height:

$h=\sqrt{13^2-(4^2+3^2)}\\\\h=12\ cm$

#The volume of the beam can then be calculated as:

$V=lwh\\\\=4\times 3\times 12\\\\=144\ cm^3$

Hence, the beam's volume is $144\ cm^3$
