Answer:
x=3 and x=-1.25
Step-by-step explanation:
4x^2-7x=15
subtract 15 from each side:
4x^2-7x-15=0
factor (trying different numbers that the sum is 7 and the quotient is 15)
(2x-6 )(2x+2.5 )=0
2x-6=0 add 6 to each side
2x=6
x=3
2x+2.5=0 subtract 2.5 from each side
2x=-2.5
x=-1.25
D=426-48(21)
I got 18 days.
So, D=18
Hope this helps! :)
The answer is 212 because you subtract 550-338 equaling 212
Answer:
4x^11+x^7+3x^3-5x+9
Its highest to lower based on the exponential number
our exponential numbers are: 3, 1, 7,0,11 putting those from highest to lowers would put them: 4x^11+x^7+3x^3-5x+9
Answer:
