use the number it and equation it with number and new number will form
Answer:
a = -10
Step-by-step explanation:
-0.4a + 3 = 7
subtract 3 from each side
-0.4a + 3-3 = 7-3
-.4a = 4
Divide each side by -.4
-.4a/ -.4 = 4/-.4
a = - 10
<span>3x^3 + 7x^2 - 7x - 3</span>
= (x + 3)(x - 1)(3x + 1)
answer
other two factors (3x + 1) and (x - 1)
Let the # be n.
Then 8(1/n) = 4(1/6). Mult both sides by 6n to elim. the fractions:
6n(8) 6n(4)
------- = -------- => 48 = 4n, and so n = 12 (answer)
n 6
