Algebraic expressions are expressions that are represented by variables and constants

The different ways to present algebraic expressions without changing their meaning is by using an equivalent expression

<h3>How to write an algebraic expression differently</h3>

To rewrite an algebraic expression without changing its meaning, we simply rewrite the expression using an equivalent expression.

Assume the expression is:

2x + 3

Another way to write the above expression is:

3 + 2x

This is so because both expressions are equivalent

Hence, the different ways to present algebraic expressions is by using an equivalent expression

Christopher swam laps everyday in the town swimming pool. He swam 45 minutes each day, five days each week, for twelve weeks.in
anyanavicka [17]
This is simple conversion.
Start from getting the numbers of hours.
12 weeks × 5 days × 45 minutes will get the number of minutes spent total (2700mins). Divide this by 60 min to get the number of hours spent total - 45 Hours.

to get the rate - r=laps/time
1800laps/45 hours
rate = 40laps/hour

△ABC has vertices A(1,1) B(5,5) and C(4,6)
stira [4]

Length in units:

Use phytogoras theorem or measure it by a ruler if your using a graph paper

AB = 5.65 units

AC = 5.83 units

CB = 1.41 units

Perimeter =5.65 + 5.83 + 1.41 = 12.89 units

Area = 1/2 * 1.41 * 5.65 = 3.98units

Find the base of a parallelogram with a slant height of 7cm and an perimeter of 63 cm2
vlada-n [284]

Base of parallelogram b = 24.5 cm

Step-by-step explanation:

We are given:

Perimeter =P= 63 cm^2

Slant Height =a= 7 cm

Base of Parallelogram =b= ?

The formula used is:

Perimeter = 2(a+b)

where a is height and b is base

Putting values:

Perimeter = 2(a+b)\\63=2(7+b)\\63=14+2b\\2b=63-14\\2b=49\\b=\frac{49}{2}\\b=24.5

So, Base of parallelogram b = 24.5 cm
