To factor 8x^2 + bx + 3, a student correctly rewrites the trinomial 8x^2 + px + qx + 3. What is the value of pq?

1 answer:

8 0

Try this option:
1. if 8*x²+b*x+3=8*x²+p*x+q*x+3, then ⇒ b=p+q.
2. p*q = max_value (b²/2), if p=q=0.5*b, and p*q→-oo, if p>0 and q<0 or p>0 q<0.
3. example:
given 8x²+10x+3, the student rewrites it as a) 8x²+5x+5x+3 (5*5=25-max value); b) 8x²+0.01x+9.99x+3 (9.99*0.01=0.0999→0); c) 8x²-20x+30x+3 (p*q=-600).

answer: (-oo;0.5b²)

Someone please help on this problem ?

Wewaii [24]

Answer:

CR = 17 ; PR = 30

Step-by-step explanation:

From the problem hypothesis we know that CD⊥PR or CQ⊥PR(perpendicular) and ∡PCQ ≡∡RCQ (bisector)

so ∡PCQ≡∡RCQ

[CQ]≡[CQ] (common side)

CQ⊥PR

--------------------------------------------

⇒(cathetus - angle case of congruence)⇒ ΔPQC≡ΔRQC so [PQ]≡[QR] (=15) // PR = PQ+QR ⇒ PR=30

from this congruence ⇒ΔPRC = isosceles so PC=CR=17

Hint: in any triangle is bisector of an angle it is perpendicular on the opposite side then triangle is isosceles.

Troyanec [42]

Answer:

$6\ plants$

Step-by-step explanation:

Remember that

$2\frac{1}{2}\ hours=\frac{5}{2}\ hours$

Using proportion

$\frac{15}{(5/2)}\frac{plants}{hours} =\frac{x}{1}\frac{plants}{hour}\\ \\x=15*2/5\\ \\x=6\ plants$

Usimov [2.4K]

Answer:

Step-by-step explanation:

The diameter is the same length as the side of the square.

The radius of the circle is 16/2 = 8

Area = pi * r^2

Area = 3.14 * 8*8

Area = 64 * 3.14

Area = 200.96 in^2
