I dont know how to solve this but heres a suggestion: Use PEMDAS
Answer:
Yes
Step-by-step explanation:
They are similiar because the big triangle is a dialated version of the first one
Set up an equation and solve:
2x-14=52
2x=66
x=33
sydney is 33 and devaughn is 19
So the expression is:

You can combine like terms, which are terms that contain the same variables raised to the same power. That means you can combine the two

.

The other terms can't be combined.
Your final answer should be

.
Answer:
$29000 with a margin of error of $5000
Step-by-step explanation:
We have that the midpoint between the given values is
(X1+X2) / 2 = ($34000+$24000)/2 = $29000
We have that the midpoint between the given values would be
(X2-X1)/2=($34000-$24000)/2=$10000/2=$5000
So I can write that approach as $29000 with a margin of error of $5000
Done
