Answer:
x = - 5, x = - 3
Step-by-step explanation:
Given
x² + 15 = - 8x ( add 8x to both sides )
x² + 8x + 15 = 0 ← in standard form
Consider the factors of the constant term (+ 15) which sum to give the coefficient of the x- term (+ 8)
The factors are 5 and 3, since
5 × 3 = 15 and 5 + 3= 8, thus
(x + 5)(x + 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x + 3 = 0 ⇒ x = - 3
The answer is 84 because 21 times 4 equals 84
Step-by-step explanation:
G Brock 85 is equal to 5 cubic flask bracket 5 Time 5 G briquettes 5 bracket equals to 5 cubic plus bracket 5 x 5 bracket is equal to 125 + 25 is equals to 150
Place value of 4 is 4/100
Given:
It is given that
Probability of winning $ 0 =
Probability of winning $ 100 =
Probability of winning $ 200 =
Probability of winning $ 500 =
To find the probability of not winning a cash prize.
Explanation:
Not winning cash prize = winning $ 0
So,
Probability of not winning a cash prize
= Probability of winning $ 0
=
Therefore,
The probability of not winning a cash prize is . Option D.
