Answer:

14.6+4x

Step-by-step explanation:

permimeter=length(2)+width(2)

7.3+x would be the length

so if you multiplied (7.3+x)2, you would get 14.6+2x if you distributive property.

Then if you multiply the width, x, by 2, you get 2x.

So we would get 14.6+2x+2x when we add them together.

And that would be 14.6+4x if you combine like terms.

And that would be your answer.

After a party, Brendan had left over pizza. Brendan had one half of a cheese pizza, 3/4 of a sausage pizza, and 2/6 of a peppero

muminat

3/4+2/6+1/2 = 9/12+4/12+6/12 = 19/12 Brendan has 1 7/12 leftover pizzas. THis is achieved by multiplying for a common denominator and adding

19/12-2/3 = 19/12-8/12 = 11/12 Brendan has 11/12 more pizzas than Steve.

What is the domain and range for:<br> y = arcsin(tanx)

Semmy [17]

The graph looks like this, on the enclosed pic:
One feature is that it's periodic and torn (has cut-off points), meaning the domain is the same as in case of tan(x): x€R and x =/= π/2+πn.
The range equals the range of arcsin(x): -π/2<=y<=π/2 OR y€[-π/2;π/2]
Hope could understand and if it helped! :)
