Answer:
4x^2 - 16x - 48 = 0.
Step-by-step explanation:
In a factor form it is:
4(x + 2)(x - 6) = 0
Convert to standard form:
4(x^2 - 4x - 12) = 0
4x^2 - 16x - 48 = 0.
Since 1000ml is 1L, 100 ml is 1/10L.
So 100ml costs 7p
And 400ml costs 28p.
There are 5280 feet in a mile
45 * 5280 = 237600
there are 3600 seconds in an hour (60 minutes time 60 seconds)
so we have 237600 feet in 3600 seconds
237600 / 3600 = 66 feet per second.
Step-by-step explanation:
3x² + 22x + 35 = 0
(3x + 7)(x + 5) = 0
3x + 7 = 0
x = -7/3
or x+5 = 0
x = -5
