Answer:
a = p * q
b = p * s + q * r
c = r * s
Step-by-step explanation:
In the trinomial ax² + bx + c
a is the coefficient of x²
b is the coefficient of x
c is the numerical term
∵ The trinomial is ax² + bx + c
∵ Its factors are (px + r) and (qx + s)
∴ ax² + bx + c = (px + r)(qx + s)
∵ (px + r)(qx + s) = (px)(qx) + (px)(s) + r(qx) + (r)(s)
∴ (px + r)(qx + s) = pqx² + (psx + qrx) + rs
∴ ax² + bx + c = pqx² + (ps + qr)x + rs
→ By comparing the two sides
∵ ax² = pqx² ⇒ divide both sides by x²
∴ a = pq
∵ bx = (ps + qr)x ⇒ Divide both sides by x
∴ b = ps + qr
∴ c = rs
∴ a = p * q
∴ b = p * s + q * r
∴ c = r * s
Answer:
The total amount of recyclables sorted by Amirah is 931 pounds.
Step-by-step explanation:
Amount of cans and bottles sorted = 263 pounds
Amount of paper sorted = 668 pounds
So, the total amount of recyclables sorted
= amount of cans and bottle sorted + amount of paper sorted
= 263 pounds + 668 pounds
= 931 pounds
Hence, the total amount of recyclables sorted is 931 pounds.
