20 x 12 = 240
20 x 8 = 160
240 + 160 = 400
answer is (B)
Answer:
three fourths is greater xx.
Step-by-step explanation:
One foot is 12 inches so 36/12=3 so 3 feet
Let A(4,12) and B(6,18)
RATE OF CHANGE = m = (y₂ - y₁) / (x₂ - x₁) = (18-12)/ (6-4)
m= 6/2 or m = 3
200 root 3;
20 * (10 root 3) is equal to 20 * 10 * root 3, so you can multiply the first 2 (the 20 and 10) and leave the root 3 at the end.
