( y - 4 ) ( y² + 4 y + 16 ) =
= y³ + 4 y² + 16 y - 4 y² - 16 y - 64 = y³ - 64
If the result is the polynomial of the form:
y³ + 4 y² + a y - 4 y² - a y - 64
a = 16
Step-by-step explanation:
-w - 11 < or = w - 5
-2w - 11 < or = -5
-2w < or = -16
w > or = -8
So, she buys 16 bags, each of them weights

pounds.
to find how many pounds of soil she bought, we have to multiply:
16*

=//16 is equal to 8*2, so we can simpify:
2*

which is 2*5=10
so in the end she bought 10 pounds of soil!
R^2/2(pi/180*D-sin(D)) is the formula so 6^2/2(pi/180*120-sin(120)) is the problem which comes to about 22cm^2
Answer: 70.74
Step-by-step explanation:
A Nonagon has 9 equal sides, and each side of the given is 7.86
So 7.86 multiplied by 9 is 70.74
