Answer:
a = 1
b = -1
c = -2
Step-by-step explanation:
We reorder the equation in such way that let us see the usual
ax² + bx + c = 0
Then the original quation is:
-2 = - x + x² - 4 ⇒ 0 = 2 - x + x² - 4 ⇒ x² - x - 2 = 0
Now we are able by simply inspection to identify a, b . c comparing our equation with the general equation so :
a = 1
b = -1
c = -2
Answer:
H

Step-by-step explanation:
8^x= 64
8²= 64
In logarithmic form,
log(base 8) 64= 2
Answer:
$77.4
Step-by-step explanation:
GIVEN: On the trip from KC to Springfield, the church van consumed
gallons of gas to go
miles. If gas cost
per gallon.
TO FIND: Cost of a round trip to Springfield.
