Yes julia is correct the run of the scond similar triangle will be b2=25.
<h3>What are simlilar traingles?</h3>
The similar triangle are those whose three sides or one angle or two sides or two angles one side are equal.
In the given:
Height of first triangle h=3
Base of first traingle =10
Height of second triangle =7.5
The base of second triangle b2 = ?
From the triangle similarity




Thus julia is correct the run of the scond similar triangle will be b2=25.

Answer: B
Negative a squared b and 5 a squared b
Step-by-step explanation:
Given that:
Negative a squared b + 6 a b minus 8 + 5 a squared b minus 6 a minus b. That is,
- a^2b + 6ab - 8 + 5a^b - 6a - b
Collecting the like term by rearranging the expression
5a^2b - a^2b + 6ab - 6a - b
The like terms in the expression above are
5a^2b - a^2b.
The correct option is B:
Negative a squared b and 5 a squared b or (-a^2b and 5a^b)
This is completing the square:
(x^2+12x+36)+42-36
Answer: (x+6)^2 +6
