I used bionomial expansion up to and including the term




n = 5
x =

Binomial expansion:

Therefore:

=

Multiply by -243
=
Answer:
A. 9
Step-by-step explanation:
Triangle Inequality: the lengths of any two sides of a triangle add up to more than the third side.
B. 10 can't be the answer because the 4 cm and 6 cm sides would just meet at a point on the 10 cm sides.
C. 11 and D. 12 can't be answers because the 4 cm and 6 cm sides would not meet (kind of like windshield wipers that are too short).
Answer:
x = 24
Step-by-step explanation:
Step 1:
x/4 - 9 = - 3 Equation
Step 2:
1/4x - 9 = - 3 Turn x/4 into 1/4x
Step 3:
1/4x = 6 Add 9 on both sides
Answer:
x = 24
Hope This Helps :)
Because we are dealing with area, we have to square the difference of the 2 polygons.40 / 15 =
<span>
<span>
<span>
2.6666666667
</span>
</span>
</span>
<span>
<span>
<span>
2.6666666667^2 = </span></span></span>

7.1111111111

So, the 40 yard polygon has <span>

7.1111111111</span>times the area of the 15 yard polygon.
