artcher [175]

Don't forget the invisble negative ones to distriute
do inside to outside

{n-1-1[n-1-1(n-1)]}
do inside
{n-1-1[n-1-n+1]}
simplify inner parenthasees

{n-1-0}
add
n-1-0=n-1

it is n-1 simplified

Supplementary angles add to?<br><br>Advanced: Write an equation and solve for x in the diagram

Ray Of Light [21]

Supplementary angles add up to 180 degrees.

7x + 3x = 180 degrees.

Combine like terms.

10x = 180 degrees.

Divide both sides by 10

x = 18

Solve: let f(x)=2x-1 and g(x)=x^2-4. find g(f(x))

Stella [2.4K]

<h3>Answer: g(f(x)) = 4x^2 - 4x - 3</h3>

Work Shown:

g(x) = x^2 - 4

g(f(x)) = ( f(x) )^2 - 4

g(f(x)) = ( 2x-1 )^2 - 4

g(f(x)) = (2x-1)(2x-1) - 4

g(f(x)) = 4x^2-2x-2x+1 - 4

g(f(x)) = 4x^2 - 4x - 3

Three commercials are played in a row between songs on the radio. The three commercials fill exactly 3

SOVA2 [1]

According to the information given, it is found that the third commercial was 1.233 minutes long.

<h3>How is the time divided?</h3>

The total time is of 3 minutes.

The first commercial uses $\frac{1}\frac{1}{6} = \frac{1} + \frac{1}{6} = \frac{7}{6}$ minutes.

The second commercial uses $\frac{3}{5}$ of a minute.

The third commercial uses x minutes.

The sum of the time used by the three commercials is 3, hence:

$\frac{7}{6} + \frac{3}{5} + x = 3$

$\frac{35 + 18 + 30x}{30} = 3$

$53 + 30x = 90$

$30x = 37$

$x = \frac{37}{30}$

$x = 1.233$

The third commercial was 1.233 minutes long.
