Given:

From the given options

the range of tanx and cotx are all real numbers

as the period of tanx and cotx are π

where as range of secx is all real numbers except π/2 + n*π i.e.

(-∞ , -1] U [1 , + ∞)

And range of cscx is all real numbers except n*π i.e.

(-∞ , -1] U [1 , + ∞)

So from the given option:

Stacy and Neil painted 280 ft of their living room wall with 4/5 gallon of paint. How many square feet can they paint with 3 gal
barxatty [35]

Step-by-step explanation:

4/5 gallons for 280 ft² (the ² is missing in the question ...).

3 gallons would be 15/5.

so, what do I need to multiply 4 with to get 15 ?

4×x = 15

x = 15/4

multiplying now also 280 ft² with this factor gives us the answer :

280 × 15/4 = 70 × 15 = 1050 ft²

they can paint 1050 ft² with 3 gallons of paint.

9(5x + 1) ÷ 3y
alexdok [17]

The expression obtained after solving the given expression is,\rm \frac{(15x+3)}{y}

<h3>What is a BODMAS rule?</h3>

For the Bracket, Order, Division, Multiplication, Addition, and Subtraction rules, BODMAS stands for Bracket, Order, Division, Multiplication, Addition, and Subtraction.

Given expression ;

9(5x + 1) ÷ 3y

Follow the BODMAS rule;

Step 1; Divide

\rm \frac{9(5x+1)}{3y} \\\\ \frac{3(5x+1)}{y} \\\\

Step 2; Multiply

\rm \frac{9(5x+1)}{3y} \\\\ \frac{(15x+3)}{y} \\\\

Hence the expression obtained after solving the given expression is,\rm \frac{(15x+3)}{y}

To learn more about the BODMAS rule, refer to brainly.com/question/23827397.
