# Thread: write algebraically

1. ## write algebraically

Find the Value of x (show full working and use coded reasons to show your decision)
(See attachment)

also some help with these:
Write the Following Algebraic Expressions.
a) the product of 2x amd 3y (does product always mean adding?)
b) the total cost of P Pens at $d each and M penciles at$n each.
c) the average of a,b and c

The $2x^x$ is an angle? And the $(3 \times 10)^x$ is the base length?

I'm sorry, but there isn't much information here and the diagram is hard to read.

a) Product means to multiply, sum means to add. So your answer is 6xy.

b) Pd + Mn dollars.

c) $\frac{a + b + c}{3}$
Add all the numbers and divide by the number of numbers.
