Area of a square is length squared and of a triangle is (length x width)/2. Also keep in mind we can make it 8 triangles with the length and width as 6 and 0.4ft so...
0.8 ^2 = 0.64
6 x 0.4 = 2.4 x 8 =19.2
19.2 + 0.64 = 19.84

What are the solutions to the following system of equations? Select the correct answer below. y = x^2 − 4x + 3 2x + y = 6
ELEN [110]
2x+y=6

y=6-2x and y=x^2-4x+3

The solution occurs when they are equal so we can say y=y which is:

x^2-4x+3=6-2x  add 2x to both sides

x^2-2x+3=6  subtract 6 from both sides

x^2-2x-3=0  factor

(x+1)(x-3)=0

So x=-1 and 3, using y=6-2x we find the corresponding y values...

y(-1)=6--2=8, y(3)=6-6=0 so the two solutions are the points:

(-1,8) and (3,0)

Two truckers leave from the same point driving in opposite​ directions, the first trucker driving at 62 miles per hour and the s
Elodia [21]

Answer:

1 hour 42 minutes

Step-by-step explanation:

Given: Speed of 1st trucker= 62 mph

           Speed of 2nd trucker= 66 mph

           Total distance need to cover to be in contact is 270 miles

           1st trucker start 1 hour ahead of 2nd trucker

Lets assume 2nd trucker take `x` hours to be in contact and 1st trucker take `(x+1)` hours.

We know, distance= speed\times time

1st trucker, distance(d_1)= 62\times (x+1)

                     ∴ d_1= 62x+62

2nd trucker, distance(d_2)= 66\times x

                    ∴d_2= 66x

Now, putting the values in an equation.

d_1+d_2= 270

⇒ (62x+62)+66x= 270

Opening the parenthesis to solve and subtracting both side by 62

⇒ 122x= 208

∴ x= \frac{208}{122} = 1.70\ h = 1 hour 42 minutes

∴ It will take 1 hour 42 minutes to be able contact each other after first trucker leaves.
