Area=width*length. Let width=x ft, then length=3x ft, given the information in the problem. The area of basement=x*3x=768, 3x^2=768, x^2=256, x=16. The width is 16 feet. Therefore, length=3x=3*16=48 feet.
Answer:
130,110,40,90,165
Step-by-step explanation:
supplementary angles add up to 180
so 180-50= 130
180-70=110
etc
its 7 because 7*7=49 and 49*7=343
so the cube root of 343 would be 7
