The artist will need 24 tan tiles. This is because 16 divided by 2 is 8, and 3 times 8 is 24.
Factor out the GCF
15x^2+20x
15x^2/5x= 3x
20x/5x= 4
Final answer: 5x(3x+4)
Answer:306
Step-by-step explanation:
since the width of the bottom square is 10, you split it between the triangles on top. You have to do this because 7 is not the whole width of the two triangles. So then the width of the triangles would be 12, 12 times 9 is 108, you'd have 216 total for both triangles and then the area of the square is 90, 90 plus 216 is 306.
