The answer to the expansion of the expression, 3+5^2 is 28

<h3>How to expand an expansion</h3>

An expansion of an expression is the evaluation of the expression to its simplest form

Given:

3+5^2

= 3 + 5²

= 3 + (5 × 5)

= 3 + 25

= 28

Therefore, answer to the expansion of the expression, 3+5^2 is 28

Answer:

After 33 weeks.

Step-by-step explanation:

Let w be number of weeks.

We have been given that Gina opened a bank account with $40. She plans to add $20 per week to the account and not make any withdrawals. So the balance after w weeks will be 20w+40.

To figure out number of weeks Gina will have exactly $700 in her account, we will equate the balance after w weeks to 700.

$20w+40=700$

Let us subtract 40 from both sides of equation.

$20w+40-40=700-40$

$20w=660$

Upon Dividing both sides of our equation by 20 we will get,

$\frac{20w}{20}=\frac{660}{20}$

$w=\frac{660}{20}$

$w=33$

Therefore, after 33 weeks Gina will have exactly $700 in her account, excluding interest.

• In Mathematics, algebra is a branch which only deals with symbols and the rule for the manipulation of these symbols. Algebra is divided into different sub branches such as advanced algebra, linear algebra, elementary algebra, abstract algebra etc.

• The basics of algebra contains numbers, variables, constants, expressions and equations. The basic four operations of algebra are addition, subtraction, multiplication, division.

Let the first consecutive odd integer be x

Second consecutive integer = x+2

Third consecutive integer = x+4

We are given that

First + third = 5(Second) – 63

x + x + 4 = 5 (x+2) -63

2x + 4 = 5x +10 -63

-3x = -57

3x = 57

x = 19

First Consecutive odd = 19

Second Consecutive odd = 21

Third Consecutive odd = 23
