Step-by-step explanation:
(a)
(x + 2)(x + 12) ← expand using FOIL gives
x² + 14x + 24 ≠ x² + 10x + 24
(b)
consider the factors of the constant term (+ 24) which sum to give the coefficient of the x- term (+ 10)
the factors are + 6 and + 4 , since
6 × 4 = 24 and 6 + 4 = 10 , then
x² + 10x + 24 = (x + 6)(x + 4)
The answer is 29
let n be the first of the consecutive odd numbers
⇒ n, n+2, n+4 n+6, n+5
represent 5 consecutive odd numbers
sum = n+ (n+2) + (n+4) + (n+6) + (n+8) = 5n+20
⇒ 5n +20=145
Solve for n = 25
25, 27, 29, 31, 33
25+27+29+31+33=145

Answer:
You have a chance of getting any of those.
Step-by-step explanation:
If you were to flip the first coin, and it would be either heads or tails 50% chance.
If you flipped the second coin, without cancelling the first, it would be 25% chance
If you flipped the third coin, without cancelling the first it would be 12.5% chance
(this is all for heads)
Q=p(r+s)
Divide by (r+s)
q/r+s=p
