Answer:
it would be 103/25
Step-by-step explanation:
Area of a triangle is equal to 1/2 b(h) so since you already have the height and base, all you need to do is input it back into the equation:

(10)(13)
Multiply 10 & 13 to equal

(130)
Then take half of 130 to get
A = 65
V = 297 for a square pyramid, I hope its right..
Answer: 72*x+12*y-(60)=0
72x + 12y - 60 = 12 • (6x + y - 5)
12 = 0
Step-by-step explanation:
Area is square units, so the new area would be the scale factor squared:
Scale factor is 2, so the area would increase by 2^2 = 4
The answer is B.4
