Which of the following statements show correct ways to find 7x198 select all that apply 7x198=(7x200)+(7x2). 7x198=(7x200)-(7x2) 7x198=(7+100)x(7+90)x(7+8) 7x198=(7x100)x(7x90)x(7x8) 7x198=(7x100)+(7x90)+(7x8)
- 7x198=(7x200)+(7x2)
- 7x198=(7x100)+(7x90)+(7x8)
The correct ways to find 7x198 are:
1. 7x198=(7x200)+(7x2)
2. 7x198=(7x100)+(7x90)+(7x8)
To find 7x198, you need to multiply 7 by 198. Let's evaluate each statement to see which ones are correct.
Statement 1: 7x198 = (7x200) + (7x2)
To find 7x198 using this statement, you would calculate:
7x200 = 1400
7x2 = 14
Then, you add them together:
1400 + 14 = 1414
Statement 2: 7x198 = (7x200) - (7x2)
To find 7x198 using this statement, you would calculate:
7x200 = 1400
7x2 = 14
Then, you subtract them:
1400 - 14 = 1386
Statement 3: 7x198 = (7+100) x (7+90) x (7+8)
To find 7x198 using this statement, you would calculate:
7+100 = 107
7+90 = 97
7+8 = 15
Then, you multiply them together:
107 x 97 x 15 = 158,295
Statement 4: 7x198 = (7x100) x (7x90) x (7x8)
To find 7x198 using this statement, you would calculate:
7x100 = 700
7x90 = 630
7x8 = 56
Then, you multiply them together:
700 x 630 x 56 = 24,384,000
Statement 5: 7x198 = (7x100) + (7x90) + (7x8)
To find 7x198 using this statement, you would calculate:
7x100 = 700
7x90 = 630
7x8 = 56
Then, you add them together:
700 + 630 + 56 = 1,386
Based on the calculations, the correct ways to find 7x198 are:
- Statement 2: 7x198 = (7x200) - (7x2) = 1386
- Statement 4: 7x198 = (7x100) x (7x90) x (7x8) = 24,384,000
