Step-by-step explanation:

Given :You deposit $365 into a savings account. After one year, the amount in the account is $428 .

To Find : Which expression describes the percent of increase in the account balance?

Solution :

let x be the percent of increase in the account balance .

Since she had $365

after one year she has $428

increased amount = 428-365 =$65

Thus the expression describes the percent of increase in the account balance :

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
