Answer:
15 sq. cm.
Step-by-step explanation:
Each of the full squares are 1 so each of the half squares are .5
There are 12 full squares and 6 half squares. If you add those half squares you will get 15 sq. cm.
Answer:
4 hours and 20 minutes
Step-by-step explanation:
I'll add the steps if you want me to.
Answer:
Its similar because they're the same lines and angles, just different sizes.
Step-by-step explanation:
If you were to flip the smaller one into the bigger one, then make the smaller one the same size as the bigger one, It would be the same size and shape. With all the same angles.

Length = x+5</h3>
If you were to use the FOIL rule and multiply out (x+3)(x+5), you would get x^2+8x+15
F = multiply first terms = x*x = x^2
O = multiply outer terms = x*5 = 5x
I = multiply inner terms = 3*x = 3x
L = multiply last terms 3*5 = 15
The four terms we get are x^2, 5x, 3x and 15
Add them up. Combine like terms
x^2+5x+3x+15 = x^2+8x+15
Therefore, (x+3)(x+5) = x^2+8x+15
---------------
With factoring, we think of this process in reverse
What two numbers multiply to 15 and add to 8? Those two numbers happen to be 5 and 3 which is where the (x+5)(x+3) comes from
Because everything below 5 rounds down and everything about 5 rounds up 8.961 would round to 9.
