Answer:
Expression.
Step-by-step explanation:An expression containing variables, numbers, and operation symbols is called an algebraic expression. is an example of an algebraic expression. Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables.
Answer:
Graph has been shown in the attached file.
Step-by-step explanation:
We have to graph the linear equation 
We can graph this by table method. Let us make a table by taking some random values of x and find the corresponding y values.
On simplifying this equation, we get
Now, we make a table for x and y values. Then we plot the points in the xy-plane and then join them to get the graph.
The table and the graph of the equation is shown in the attachments.

The length of the ramp calculated using Pythagoras is approximately 350 cm
From the diagram attached :
- Height of ramp = opposite = 225 cm
- Angle of inclination, θ = 40°
Using Pythagoras ; the length of the ramp can calculated as follows :
Sin θ = opposite / hypotenus
Sin 40° = 225 / hypotenus
Cross multiply
Hypotenus × 0.6427876 = 225
Divide both sides by 0.6427876 to isolate the hypotenus
Hypotenus = 225 / 0.6427876
Hypotenus = 350.03786 cm
Therefore, the length of the ramp which is the hypotenus is approximately 350 cm
