4立方體體積是8，那一個面的面積當(dāng)然是4咯
5. Ms.Smith got an 8 percent cost-of-living raise of $20 per week
Ms.Smith's new weekly salary $260
5 x*0.08=20，那x+20=270>260

A. a2+ab B a2+ab+a C a2+a+b D a3+a2b E a3+a2b+a2

答案是D，題目我都看不懂，是啥意思呢?
這是說秘書打六封信，沒一封信要1頁或者兩頁。如果秘書總共打了10頁，那么有多少封信是兩頁?

a.none b.one c.two d.there e.four
我覺得這道題除了2不可能,其它四個數(shù)都有可能.可答案是c,想問大家為什么?
題目意思是這5個數(shù)哪些可以是2個>1的數(shù)的積,一個是奇數(shù),一個是整數(shù),只有6和14的因數(shù)中有奇數(shù),所以C.
10 這句話大家看該怎樣列式子呢?這是一道圖表題.

是這樣(1970-1965)/1965還是(1970-1965)/1970這樣?
是這樣:(1970-1965)/1965
