Think it's 400
7/8 x 3200= 3200/8= 400 400x 7 =2800
3200 - 2800= 400
so 1/8 of 3200 = 400
First of all, we know that 
because of its vertical angle. 
is also equal to 
because it's an interior angle.
A = 1/2 h (a+b)
A / 1/2 h = a + b
A / 1/2 h - b = a
a = A / 1/2 h - b
Hope this helps
Answer:
a. (3x^4 + 6 ) + (2x^2)
b. (X^3 ) + (-x -7)
c. (4.6x^4) + (-1.5x^2)
Step-by-step explanation:
For the first one, we have to write to polynomials, which equal 3x^4 + 2x^2 +6
One possible solution is (3x^4 + 6 ) + (2x^2)
For b, we can do,
(X^3 ) + (-x -7)
And finally for c, we can write,
(4.6x^4) + (-1.5x^2)
7 is a prime number, 72 is not a prime number.
Hope this helped!:)
