Answer:
1,560,000 mm²
Step-by-step explanation:
A= 
This would make shape A's area <u>480,000</u>.
B= 
This would make shape B's area <u>180,000</u>.
C= 
This would make shape C's area <u>300,000</u>.
D= 1000×600 This wouls make D's area <u>600,000</u>.
Now you add up all of the areas;
480,000+180,000+300,000+600,000= 1,560,000 mm²
Like terms must have the same variables and those variables must have the same powers.
and 
are like terms, because they both have 
and they both have 
.
and 
are NOT like terms, because the powers no longer match.
In your example, do you have the same variables and do the variables have the same powers in both expressions?

Julia’s score is <em>y</em> and Tina’s score is <em>y</em> + 6.
Step-by-step explanation:
Let us take Julia’s score be <em>y</em>.
First Tina scored 4 points more than Julia, so the expression is <em>y</em> + 4.
Then, Tina earned 2 points as extra credic, now the expression becomes
(y + 4) + 2 = y + 6.
Hence Julia’s score is <em>y </em>and Tina’s score is <em>y</em> + 6.
