Step-by-step explanation:
I don't know just please guess sorry but can you mark as brainiest.
Derek ran less than 6 miles. If the race is 6 miles, and he only ran 3/8, he ran less than a half of the race. If he didn't finish the race of 6 miles, he couldn't possibly have run 6 miles.
4x^2+23x+15=0
Δ=23^2-4*4*15=529-240=289
x1= (-23+17)/8=-6/8= -3/4
x2= (-23-17)/8=-5
4x^2+23x+15= 4(x+3/4)(x+5)=(4x+3)(x+5)
