1. Last week Patrice made (15d + 400) dollars. This

week she made (10d. So) dollars. Write an expression

that represents how much money she made

altogether over the last two weeks.

 25 d+ 400

Step-by-step explanation:

Given, Last week Patrice made (15d + 400) dollars.

And this week she made (10 d) dollars.

Now , we need to find the expression that represents how much money she made altogether over the last two weeks, which is equal to

(Money made in last week) + (Money made in this week)

=  (15d + 400)+(10 d)

= 15 d+ 400+ 10 d  [ Opening Parenthesis]

= 15d+ 10d + 400  [ Commutative property]

= 25 d+ 400

i.e. The required expression = 25 d+ 400

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
