Answer:
10b +13 +18a
Step-by-step explanation:
The perimeter of a triangle= Sum of the length of all sides
Therefore,
Perimeter = (10a +9) + (8a - 3) + (10b + 7)
= 10a +8a +10b + 9+7-3
= 18a + 10b + 13
I think it’s B but hopefully i’m right good luck
Answer:
C. The factors had the same sign.
Step-by-step explanation:
Factors that had the same sign will have a positive product.
Two positive numbers will have a positive product.
For example, 3 times 3 is 9.
Two negative numbers will also have a positive product, because multiplying negative numbers by other negative numbers will cancel out the negative.
For example, -3 times -3 is 9.
So, C is correct
