you would move the decimal until you only have 1 number to the left of it and the rest on the right. we moved it three spots left in this case so your answer would be as follows.
1.8 x 10^3 is the answer
Answer:
A. 12x² + 15xy + 18x
B. - 12x² + 18xy + 24x
C. 10x² - 31x - 14
D. x² - 36
3a. x = 8
3b. x = 3
Step-by-step explanation:
A. 3x ( 4x + 5y +6 ) C. ( 2x - 7 ) ( 5x + 2 )
12x² + 15xy + 18x 10x² + 4x - 35x - 14
10x² - 31x - 14
B. 6x ( 3y - 2x + 4 )
18xy - 12x² + 24x D. ( x + 6 ) ( x - 6 )
-12x² + 18xy + 24x x² - 6x + 6x - 36
x² - 36
3a. 5/4x + 2 = 12 3b. 7/3x - 2 = 5/3x
5/4x = 12 - 2 -2 = 5/3x - 7/3x
5/4x = 10 -2 = - 2/3x
x = 10 · 4/5 -2/3x = -2
x = 8 x = 3
