Answer:
No, the area of the dilated triangle will increase by a factor of 9
Step-by-step explanation:
When the scale factor by which the dimensions is dilated = 3, we have;
The original length of base = b
The base length of the dilated triangle = 3×b
The original height of the the triangle = h
The height of the dilated triangle = 3×h
The original area of the triangle = 1/2 × base × height = 1/2×b×h
The area of the dilated triangle = 1/2 × base of dilated triangle × height of dilated triangle
∴ The area of the dilated triangle = 1/2× 3 × b × 3× h = 9×1/2× b×h
Which gives;
The area of the dilated triangle = 3²×1/2× b×h= (Scale factor)²× The original area of the triangle.
From 3² = 9, we have;
The area of the dilated triangle = 9 × The original area of the triangle.
Therefore;
The area of the dilated triangle will increase by a factor of 9.

Answer:
23x2+8xy−57y2
Step-by-step explanation:
(5x)(5x)+(5x)(7y)+(−7y)(5x)+(−7y)(7y)+−2x2+8xy+−8y2
=25x2+35xy+−35xy+−49y2+−2x2+8xy+−8y2
Combine Like Terms:
=25x2+35xy+−35xy+−49y2+−2x2+8xy+−8y2
=(25x2+−2x2)+(35xy+−35xy+8xy)+(−49y2+−8y2)
=23x2+8xy+−57y2
Plz mark brainlest :)
