(3x)^3+3(3x)^2*-1 +3(3x)(-1)^2+(-1)^3 then simply that down to 27x^3-27x^3+9x-1
all i can really say is it is a y angle
Answer for 20. is
20.answer-22
The two triangles on the side are 18 in^2 and the square in the middle is 36 in^2. So in total, it has an area of 72 in^2
I don't understand
one way you could consider 'simplifying' is to make all numbers whole and simplest form
I will put it into stardard form which is ax+by=c
make all numbers whole
2.1x-0.9y=15
multiply everybody by 10
21x-9y=150
divide everybody by 3
7x-3y=50
