15-4=11 plus
(7-5)= 2
if is times 2 is 32
if is plus 2 is 15
if is minus 2 is 11
and if is divided by 2 is 6.5
(I'm saying all that because you didn't put any symbol beside the number 2)
Answer:
8a^3.
Step-by-step explanation:
(a+b)^3=a^3+b^3+3a^2b+3ab^2
(a-b)^3=a^3-b^3-3a^2b+3ab^2
(a+b)^3+(a-b)^3=2a^3+6ab^2
According to the question
(a+b)^3+(a-b)^3+6a(a^2-b^2)
Put in the value
=2a^3+6ab^2 +6a^3–6ab^2
=8a^3
49. Straight lines always equally 180 degrees. And the angle directly below P is equivalent to the 131 angle so 180-131=49 (hope that was somewhat explained well enough because angles are hard to explain without directly showing on paper)
T= -1.4
hope the answer helps
you got to divide both sides by the number with the variable so by 5
The square root is 41.9332803391. To double check, multiply 41.9332803391 by 41.9332803391, which gave me 1758.4.
I hope this helps!
