我郁闷了!为什么它打分为5的题我觉得特别简单,然后打分为2或者3的题我倒是觉得比5要难呢、、、
1.Five different points A,B,C,D,and E lie on a line in that order.The length of AD is 4.5 and the length of BE is 3.5.If the length of CD is 2,what is one possible value for the length of BC?
2.If the length of a rectangle is increased by 30% and the width of the same rectangle is decreased by 30%,what is the effect on the area of the rectangle?
3.还有一个问题,当题目中提到" consecutive“ 这个词的时候,是正顺序还是正顺序和倒顺序都考虑?
答
1.(AD=4.5,CD=2)-->AC=2.5--> BCAB>1-->BC啊啊啊。。。我郁闷了。。。。。。。。。。。。。。。。。。。。。。原来是题看错了。。。。。。。。。。
