You need to split the shape into two then measure the shapes like trapezoids use a+b/2(h) for the formula
Answer:
There are two real and different roots
Step-by-step explanation:
The discriminant is given by b²-4ac
(-12)²-4(70×1)
144-280
136
Now 136>0
If the order does not matter, cars can be arranged in 20 ways
If an order is important, cars can be arranged in 120 ways
The probability that the three newest cars end up parked in the driveway is 0.167
1. If the order does not matter, combination is used

Here, n=6 r=3
using formula,we get

2. If an order is important, Permutation will be applicable

∴
3. the probability that the three newest cars end up parked in the driveway
P=
=
=
=
≈ 0.167
Hence, If the order does not matter, cars can be arranged in 20 ways
If an order is important, cars can be arranged in 120 ways
The probability that the three newest cars end up parked in the driveway is 0.167

The solution to the system of equation is (3/2, -1/2)
<h3>System of equations</h3>
Given the following system of equations as shown;
(3x+y=4 .... * 4
2x-4y=5 ..... * 1
_______________
12x+4y=16
2x-4y=5
Add both equations
12x+2x = 16 + 5
14x = 21
x = 3/2
Substitute x = 3/2 into any of the equation to have;
2x-4y=5
2(3/2) - 4y = 5
3 - 4y = 5
-4y = 5 - 3
-4y = 2
y = -1/2
Hence the solution to the system of equation is (3/2, -1/2)
