-5
The factors of 20 are 1,2,3,5,6,10,15, and 30
6+3=9.
Answer:
The equation is equal to each other it ends up simplifying to
8a-39=8a-39
they are both equal to each other but if you simplify it even more thye undo each other so it becomes
0=0
Step-by-step explanation:
Answer:
-0.6 cm/min
Step-by-step explanation:
The formula for the area of a triangle is ...
A = (1/2)bh
Solving for the base, we find ...
b = 2A/h
Then the rate of change of the base is ...
b' = 2(A'h -Ah')/h^2
Filling in the given values, we find the rate of change of the base to be ...
b' = 2((2 cm^2/min)(20 cm) -(160 cm^2)(1 cm/min))/(20 cm)^2
= 2(40-160)/400 cm/min
= -0.6 cm/min
The base is decreasing at 0.6 cm/minute.
