Answer:
Aaron=12 Ben=24 Caleb=29
Step-by-step explanation:
Aaron=x
Ben=2x
Caleb=2x+5
x+2x+2x+5=65
5x+5=65
-5 on both sides
5x=60
divide by 5 on both sides
x=12
You then substitute this answer with ben and Caleb
ben= 2x (2*12) =24
caleb= 2x+5 (24+5)=29
Answer:
Answer:The formula for the area of a parallelogram is A = bh, and the formula for area of a triangle is A = 1/2bh. Since a triangle is half of the area of a parallelogram with the same base and height, the only difference in the formula is 1/2.

Answer:11
Step-by-step explanation:
Step-by-step explanation:
ln(x) + ln(x + 25) = 0
ln(x(x + 25)) = 0
ln(x² + 25x) = 0
ln(x² + 25x) = ln(1) , x ≥ 0
x² + 25x = 1
x² + 25x + 625/4 = 1 + 625/4
(x + 25/2)² = 629/4
x + 25/2 = ±√(629/4)
x = ( -25 ±√629)/2
x = (-25 - √629)/2 atau ( -25 + √629)/2
(-25 - √629)/2 ≥ 0 NOT PROVED
(-25 + √629)/2 ≥ 0 PROVED
Solution → x = (-25 + √629)/2
