The model shows that we are to arrange the factors based on the terms in the square box. The factored form is(6x+5)(x-4)
<h3>Factorizing quadratic equations</h3>
Factorization is a way of simplify. Given the equation 6x² - 19x - 20
Factorize
6x² - 19x - 20
6x² - 24x + 5x- 20
6x(x-4)+5(x-4)
(6x+5)(x-4)
We are to arrange each term of the factors in the square box

Answer:
The elapsed time is 7hrs and 1 minute.
R=15
explain:
add the numbers in parentheses to get
45/3 = r
divide the numbers to get
15 = r
That's a pretty confusing one. I think it's 10 minutes.
<h2>
Automobile must travel at 96 mph to pass the truck in 4 seconds.</h2>
Step-by-step explanation:
Length of automobile = 16 feet = 4.88 m
Length of truck = 28 feet = 8.53 m
Speed of truck = 30 mph = 48 km/h = 13.33 m/s
Time in which automobile to pass truck = 4 s
Distance traveled by truck in 4 seconds = 4 x 13.33 = 53.33 m
Distance which need to cover by automobile in 4 seconds to pass truck is the sum of length of automobile, length of truck and distance traveled by truck in 4 seconds.
Distance which need to cover by automobile in 4 seconds = 4.88 + 8.53 + 53.33
Distance which need to cover by automobile in 4 seconds = 66.74 m
Distance = Speed x Time
66.74 = Speed x 4
Speed = 16.69 m/s = 60 km/h = 96 mph
Automobile must travel at 96 mph to pass the truck in 4 seconds.
