Answer:
how many miles did he run over the days ?
Step-by-step explanation:
Use FOIL to multiply binomials by multiplying each term in the first binomial by the terms in the second binomial.
(4x - 3)(x + 5)
4x^2+20x-3x-15
Now combine like terms.
answer : 4x^2+17x-15
19 = 1/2 g t²
Multiply each side by 2 :
38 = g t²
Divide each side by ' g ' :
t² = 38/g
Square root each side :
<em>t = √(38/g)</em>
