Answer:
x = ±√ 1.667 = ± 1.29099
Step-by-step explanation:
List factors of p: 3,8
List factors of q: 4,5
List possible zeros: +/- p/q (0 -8 1.667
(looked it up )
Answer: 8 X 1/2 = 4, thus you would find the number line jumping from every 1/2 finally to 4.
You haven't told us whether 9 and 12 are the two legs of the triangle, or whether the 12yd is the longest side.
<u>If the 9 and the 12 are the two legs, then</u>:
C² = A² + B²
C² = 81 + 144
C² = 225
C = <u>15 yd</u>
<u>If the 12 is the longest side, then</u>:
(12)² = (9)² + B²
B² = (12)² - (9)² = 144 - 81 = 63
B = √63 = <u>7.937</u>yd (rounded)

Factorize:
Factor out 0.4x + 6y
Express as a square:
Answer: x = b + p/a
Step-by-step explanation: First add b to both sides to get ax = b + p.
Now divide both sides by a to get x = b + b/a.
