Hello : 
let : y  the length  and : x the  width.... x< y      x<span> <span>> 0 and y</span></span><span> <span>> 0</span></span>
 y = 3+2x ....(1)
xy = 35...(2)  
subsct in (2):
x(3+2x) = 35
2x² +3x-35 = 0
delta : (3)² -4(2)(-35) = 289 = 17²
x1 = (-3-17)/4  < 0 ( refused)
x2 = (-3+17)/4 = 7/2
y = 3 +2(7/2) = 10

Which of the following is a trinomial?
Masja [62]
Although you didn't provide any answer choices:

A trinomial is an expression with exactly three terms that can't be combined an example would be this

x^2 - 3x + 1

None of those terms can be combined

x^2 + 3 - 4 has three terms but it isn't considered a trinomial because you can simplify it to x^2 - 1 which is known as a binomial because it has 2 terms in it's simplified form.

hope this helps C:

(2/5 )*(2/2)=4/10    ,    (1/2)*(5/5)=5/10
Now the dominators are the same ,you can just compare the numerators. It is 4:5
