43/9 = 4.77777777778
That is because only the most 9's that could fit into 43 is 4 which is 9 x 4 = 36. I can't really show the work, but I think Khan Academy would be a great help!
It's just a tiny bit sloppy. The 10.2 cm should be designated with a right angle too. I'll answer it that way.
Area = (L1 + L2)*h/2
L1 = 10.2
L2 = 12.2
h = 12.6
all givens are in cm.
Area = (10.2 + 12.2)*12.6/2
Area = 22.4 * 6.3
Area = 78.12 cm^2
Answer:
4(5x-2y)
Step-by-step explanation:
You can only take out the 4 because 20 and 8 are divisible by 4. You also can't take out x because it's only next to the 20 in the equation.
Answer:
Possible base lengths are 1, 2, 3, 4, 5
Step-by-step explanation:
Area = base x height / 2
Let base be b
b x 8 / 2 < 24 (Area < 24)
4b < 24
b < 6
