Answer:
Step-by-step explanation:
(x^3 + 2x − 3)(x^4 − 3x^2 + x)
Multiply each value of 2nd bracket with 1st bracket:
=x^4(x^3 + 2x − 3) - 3x^2(x^3 + 2x − 3) +x(x^3 + 2x − 3)
=x^7+2x^5-3x^4-3x^5-6x^3+9x^2+x^4+2x^2-3x
Now combine the terms with same power:
=x^7-x^5-2x^4-6x^3+11x^2-3x
You can also take the common from the expression:
x(x^6-x^4-2x^3-6x^2+11x-3)....
The product of (x^3 + 2x − 3)(x^4 − 3x^2 + x) is x(x^6-x^4-2x^3-6x^2+11x-3)....
The answer for that will be:
length of second base = 11 units
Here's how it was generated:
You have to assume first that the second base is x
This is how the mid-segment in a trapezoid is calculated:
mid-segment = (first base + second base) / 2
Let:
mid-segment = 19
first base =27
second base = x
Substitute and solve for x:
mid-segment = (first base + second base) / 2
19 = (27 + x) / 2
19 * 2 = 27 + x
38 =27 + x
Transpose the variable to the right and the constants to the left. Take note of changing signs:
x = 38 - 27
x = 11 units
Answer:
79.617...
Step-by-step explanation:
When you are trying to find the circumfrence you do c=πd
So to find the diameter you reverse it
Since you already know the 250 feet you divide it by π
You then get 79.6
