years. don states the applied interest is simple interest. true or false?
(number of years)
(future value)
$205.00
$210.00
$215.00
$220.00
$225.00
a. true
b. false

A.  True.

Step-by-step explanation:

The value increases by the same amount ($5) every year so it is simple interest.

x=30

step-by-step explanation:

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
