Step-by-step explanation:
Thanks, so cube root of 512 is 8 and reciprocal of 0.4 is 2.5 then:
8 : 2.5 / divide both by 2.5 to get:
3.2 : 1 that's my answer right?
Answer:
26x³ - 12x² + 5x + 7
Step-by-step explanation:
- (2x³ - 3x + 11) - (3x² + 1) x (4 - 8x)
- 2x³ - 3x+11 - (12x² - 24x³ + 4 - 8x)
- 2x³ - 3x + 11 - 12x² + 24x³ - 4 + 8x
- 26x³ + 5x + 7 - 12x²
= 26x³ - 12x² + 5x + 7
13xy^2-10xy-23=0
you first add the like terms and rewrite and thats how you get the answer
