Practice problem
Find the area of a triangle in terms of xxx if base=6x−2\text{base} = 6x-2base=6x−2 and height=4x+5\text{height}= 4x+5height=4x+5.
A=24x2+22x−10A = 24x^{2}+22x-10A=24x2+22x−10
A=12x2+11x−5A = 12x^{2}+11x-5A=12x2+11x−5
A=12x2−5A = 12x^{2}-5A=12x2−5
A=3x−1A = 3x-1A=3x−1
Type a concept, like “slope” or “photosynthesis”.
