Answer: A = 1032 in²
Step-by-step explanation:
two sides each of rectangles
2(10)(18) + 2(10)(12) + 2(12)(18) = 1032 in²
The dots you see on step 1 and step 2 mean to multiply
when you divide a fraction you actually multiply it then whatever you get you simplify it. simple :) hope it helped
Answer:
x = 3/4 and x = -4/5
Step-by-step explanation:
20x⁴ + x³ + 8x² + x − 12
Group:
(20x⁴ + 8x² − 12) + (x³ + x)
Factor:
4 (5x⁴ + 2x² − 3) + x (x² + 1)
4 (5x² − 3) (x² + 1) + x (x² + 1)
(x² + 1) (4 (5x² − 3) + x)
(x² + 1) (20x² + x − 12)
(x² + 1) (4x − 3) (5x + 4)
So the rational roots are x = 3/4 and x = -4/5.
