Answer:

See explanation

Step-by-step explanation:

Given:

18m + 42n

These two variables are not the same, so we can't add the two terms. However, we can factor out a number out of this expression.

The GCF of 18 and 42 is 6.

We can draw 6 out of this expression to get 6(3m + 7n).

This is an equivalent expression.

We can also draw 2 out to get 2(9m + 21n).

We can also draw 3 out to get 3(6m + 14n).

We can also draw 1/2 out to get (1/2)(36m + 84n).

There are endless possibilities, but these are a few. You get the idea!

11. The student council is comparing prices for their semi-formal dance. They compare banquet. Hall A charges $40 per person. Ha

Natalka [10]

Answer:

TC (A) = 40x , TC (B) = 500 + 20x

Step-by-step explanation:

Let the number of students be = x

Hall A Total Cost

Relationship Equation, where TC (A) = f (students) = f (x) 40 per person (student) = 40x

Hall B Total Cost

Relationship Equation, where TC (B) = f (students) = f (x) 500 fix fee & 20 per person (student) = 500 + 20x

Prove the trigonometric identity

Annette [7]

Answer:

Proved See below

Step-by-step explanation:

Man this one is a world of its own :D Just a quick question are you a fellow Add Math student in O levels i remember this question from back in the day :D Anyhow Lets get started

For this question we need to know the following identities:

$1+tan^{2}x=sec^2x\\\\1+cot^2x=cosec^2x\\\\sin^2x+cos^2x=1$

Lets solve the bottom most part first:

$1-\frac{1}{1-sec^2x} \\\\$

Take LCM

$1-\frac{1}{1-sec^2x} \\\\\frac{1-sec^2x-1}{1-sec^2x} \\\\\frac{-sec^2x}{1-sec^2x} \\\\\frac{-(1+tan^2x)}{-tan^2x}$

now break the LCM

$\frac{-1}{-tan^2x}+\frac{-tan^2x}{-tan^2x}\\\\\frac{1}{tan^2x}+1\\\\cot^2x+1$

because 1/tan = cot x

and furthermore,

$cot^2x+1\\cosec^2x$

now we solve the above part and replace the bottom most part that we solved with $cosec^2x$

$\frac{1}{1-\frac{1}{cosec^2x} } \\\\\frac{1}{1-sin^2x} \\\\\frac{1}{cos^2x}\\\\sec^2x$

Hence proved! :D

Answer:

2nd option

Step-by-step explanation:

The zeros are the points on the x- axis where the graph crosses.

Since the graph crosses the x- axis at x = - 1 and x = 5, then

The zeros are x = - 1 and x = 5
