To solve, first create a common factor for b by multiplying the 1st equation by 2 to get: 12a+2b=22.Now, add the two equations together to get: (12a+5a) + (2b-2b) = (22+19)which is 17a=41 , when simplifie...

Auxins are plant growth hormones found in both the roots and shoots of plants, in the shoots they promote growth whereas in the roots they inhibit it. In the shoots they cause cell elongation in the side ...

912 = 4(x+2)(x+9)228 = (x+2)(x+9)228 = x² + 11x + 180 = x² + 11x -210using the quadratic formula we obtain x = -10 or x = 21As dimensions must be positive; x must equal 21Hence; the ...
