I believe for number 3, the answer is x=-5 and for number 4, the answer is either x=21 or x=7

Answer:

3). -5. 4).7.

Step-by-step explanation:

3).CB + BA = CA

(x+15) + (x+13) = 18

2x + 28 = 18

2x = 18 - 28

2x = -10

x = -5.

4). ED + DC = EC

(2x - 7) + (x - 6) = 8

3x - 13 = 8

3x = 8 + 13

3x = 21

x = 7.

Question 3 Unsaved

bazaltina [42]

Answer:

Step-by-step explanation:

DE given is

y''+8y'+15y=0, y(0)=0, y'(0)=1

Take Laplace on the DE

We get

$s^2 Y(s) -sY(0) -y'(0)+8(sY(s)-y(0))+15Y(s) =0\\s^2 Y(s) -s(0) -1+8(sY(s)-0)+15Y(s) =0\\Y(s)(s^2+8s+15)-1=0\\Y(s) = \frac{1}{s^2+8s+15}$

Simplify to get

Y(s) = $\frac{1}{2}[ {\frac{1}{s+3} -\frac{1}{s+5} }]$

Take inverse

$y(t) = \frac{e^{-3t} -e^{-5t}}{2}$
