Answer:

2x+2(3)+5

Step-by-step explanation:

The first step is eliminating the brackets by multiplying everything inside the brackets by 2 which will then resulting in multiplying by 2 into x, thus having 2x+2(3)+5.

H=-16t^2+46t+6 after how many seconds will the ball hit the ground?

ANEK [815]

Ball hit the ground is when the function equals zero
0=-16t^2+46t+6
we can't factor so use quadraticformula

for
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$
x= $\frac{-46+/- \sqrt{46^2-4(-16)(6)} }{2(-16)}$
x= $\frac{-46+/- \sqrt{2116+384} }{-32}$
x= $\frac{-46+/- \sqrt{2500} }{-32}$
x= $\frac{-46+/- 50 }{-32}$
x= $\frac{-46+ 50 }{-32}$ or $\frac{-46- 50 }{-32}$
x= $\frac{4}{-32}$ or x= $\frac{-96}{-32}$
x=-1/6 or x=3

we cannot have negative time because time starts at 0
disregard -1/6 as a possible answer

answer is after 3 seconds
