Answer:
f(-5)=2, f(-2)=4
Step-by-step explanation:
-5<-4, so you use the first function in the piece wise function. You plug in -5 for x in 2^x+6, which gives you 2^1=2
-4<-2=2, so you use the second equation in the piecewise function. You plug in -2 for x, which gives you 2(-2+3)^2 +2, or 2(1)^2 +2 = 2 + 2 = 4
You need to bring the right to the left
2X^2-9x-x^2+20=0
So you combine and get
X^2-9x+20
(X-4)(X-5)
Cuz -4 times -5 =20 and -4+-5=-9
So solve X-4=0. X-5=0
X=4. X=5
<h3> <u>Answer</u><u> </u><u>:</u></h3>
<h3><u>Explaination :</u></h3>
In the question it is given that the length is 4 cm more than the width so let us assume the width as x.
Therefore,
- Length (l) = 4 + x
- Breadth = x
As we know the formula of calculating the perimeter of rectangle is,
Here,
- P is perimeter
- l is length
- b is breadth
Putting their respective values,
=> 14 = 2 (x + 4 + x)
=> 14 = 2 × (x + 4 + x)
=> 14 = 2x + 8 + 2x
=> 14 = 4x + 8
=> 14 - 8 = 4x
=> 4x = 6
=> x = 6 / 4
=> x = 3 / 2
=> x = 1.5
