Step-by-step explanation
b = 2h is given
2 b + h = 4 hours is given sub in the top equation
2 (2h) + h = 4
5h = 4
h = 4/5 hr or 48 minutes
Answer:
B
Step-by-step explanation:
the area of a parallelogram is the length of one of the sides multiplied with the length of the height on this side.
so, in this case it is
4×5 = 20 cm²
Parallel lines have same slope but different y-intercept. So they gave the equation y=4x-5 and the (0,3) where 3 is the y-intercept.
So the equation would be y=4x+3. HOPE THIS HELPS!!!!!!!!
