Simplify 9i(2+3i):
9i×2=18i
9i×3i=27i
18i+27i
Well 3.20 is 2 tenths of 1 and .02 is 2 hundredths of one so its >
Answer:
(5x² + 3) (2x-3)
Step-by-step explanation:
10x³ - 15x² + 6x - 9 (rearrange)
10x³+ 6x - 15x² - 9 (group using parentheses)
(10x³+ 6x) - (15x² + 9) (factor out 2x from first term and 3 from second term)
2x (5x²+ 3) - 3(5x² + 3) (factor out (5x²+3) )
(5x² + 3) (2x-3) (answer)
Answer:
C. 2.50, 2.51, 5.00, 5.01, 7.50, 9.00, 10.00
Step-by-step explanation:
For number 11 the third angle would be equal X as the second angle is, since the two sides next to the those angles are congruent. Then you would have to set an equation saying that 2x + 38= 180 and then you can just solve for X
