还不知道ACT数学考什么，来看看美国高考ACT数学题1

考试真题练习对于每一门科目都很重要，只有多练习考试真题，我们才会发现自己的不足之处，才能更好的完善复习计划，今天课窝小编为大家准备了一篇美国高考ACT数学题，一起来看看吧!

1. A rectangular lot that measures 150 ft by 200 ft is completely fenced. What is the approximate length, in feet, of the fence?

F. 300

G. 350

H. 400

J. 700

K. 1,400

解析：The correct answer is J. To find the length of fence needed to fence a rectangular lot 150 ft by 200 ft, you need to find the perimeter. The formula for the perimeter of a rectangle is 2 times the sum of the length and width, or P = 2( l+ w). 2(150 +200) =2(350) =700.

正确答案选J。所需篱笆的长度即为这块长150英尺宽200英尺矩形土地的周长。根据矩形周长公式，可知：矩形周长=2(长+宽)，即2(150 +200) =2(350) =700英尺。

2. The expression a[b+(c-d)] is equivalent to:

A. ab + ac - ad

B. ab + ac + ad

C. ab + ac - d

D. ab + c + d

E. ab + c - d

解析：The correct answer is A. To find an equivalent expression, multiply a by b+c-d. This results in a(b) + a(c) + a(-d), or ab + ac - ad.

正确答案选A。根据乘法分配率展开括号可得ab + ac - ad。
