Answer:
x = 7, x = 2
Step-by-step explanation:
Given
x² = 9x - 14 ( subtract 9x - 14 from both sides )
x² - 9x + 14 = 0 ← in standard form
(x - 7)(x - 2) = 0 ← in factored form
Equate each factor to zero and splve for x
x - 7 = 0 ⇒ x = 7
x - 2 = 0 ⇒ x = 2
Answer:
y=339
Step-by-step explanation:
<span>complex roots (zeros) occur in conjugate pairs __ if 7+4i is a zero, then 7-4i is also a zero
for the coefficients to be rational; any irrational zeros (sqrt(7)) must have a conjugate, so -sqrt(7) is also a zero</span>
If 2 inches equals 40 miles, then 1 inch equals 20 miles.
115 miles/20 miles=5.75
The cities would be 5.75 miles apart on the map.
