Answer:

2x+8 and 2(4+x)

garri49 [273]
Write a proportion first, change over original, like this:
 8      x
16   100
(I got 8 because the difference between 24 and 16 is 8 and I got 100 because percents are out of 100.)
Cross multiply 8 by 100 and you get 800.
Divide 800 by 16 and you get 50.
It changed by 50%

Given any two numbers, which is greater, the lowest common multiple of the numbers or the greatest common multiple?
tester [92]

After you've calculated a least common multiple, always check to be sure your answer can be divided evenly by both numbers. Find the LCM of these sets of numbers. Multiply each factor the greatest number of times it occurs in any of the numbers. 9 has two 3's, and 21 has one 7, so we multiply 3 two times, and 7 once.

olganol [36]

Answer:

32

Step-by-step explanation:

Area of a big right triangle = 1/2 * 4 * (2+2+6) = 1/2 * 4 *10 =20

Area of a left right triangle = 1/2* 2*2 = 2

Area of a right right triangle = 1/2 * 6*2 =6

Area of a square = 2*2 = 4

All together:

20+ 2+6+4 =32
