4/2 * 4/5 = (4*4) ^ (2*5) = 1 3/5 = 1.6
A=1/2(b+b)•h
A=1/2(18+24)•8
A=1/2(42)•8
A=21•8
A=168ftsq
Answer:
1.5 hours
Step-by-step explanation:
using the relationship between distance/ speed / time
distance = speed × time
speed = 
= 
= 62 mph
travelling at this rate then
time = 
= 
= 1.5 hours
Answer:
0
Step-by-step explanation:
1) Multiply the first equation by -3: -6x - 3y = 12
2) Substitute 2x + 12 for -3y in the above equation, obtaining:
-6x + 2x + 12 = 12
Then -4x = 0, and x = 0. Letting x = 0 in the first equation, we get:
0 + y = -4, so y = -4.
The x-value at the intersection of the lines is zero (0).
That intersection is at (0, -4).
