(6x^3-2x^2+4) <span>- (2x^3+4x^2-5)
Subtract the like terms
6x^3 - 2x^3 = 4x^3
-2x^2 - 4x^2 = -6x^2
4 - (-5) = 9
The final answer would be
4x^3 - 6x^2 + 9

Irrational numbers. √7 is an irrational number.
Answer:
27 inches
Step-by-step explanation:
We are using the Pythagorean theorem
a^2 +b^2 = c^2 where c is the hypotenuse
We are given the diagonal, which is the hypotenuse and a leg
36^2 + b^2 = 45^2
Subtract 36^2 from each side
36^2 + b^2 - 36^2 = 45^2 - 36^2
b^2 = 45^2 - 36^2
b^2 =2025-1296
b^2 =729
Take the square root of each side
sqrt(b^2) = sqrt(729)
b =27
8a+4s=840
a=s+30
8(s+30)+4s=840
12s+240=840
12s=600
s=50
A=s+30
a=50+30
a=80
