Algebra I need the formula not the answer
TYPO 169cm^2 My apologies.

Algebra I need the formula not the answer
If the sides of a square are lengthened by 8cm the area becomes 169^2. Find the length of a side of the original square. I am getting 34.25cm

-5x^3+7x^2+9x+5 The degree of the polinomial is 5?

Algebra
would the GCD for -42a^2 and 7a^5 be 7a?

Algebra
10^7x8.48= 848,000,000?

Algebra
GCF for the group of terms -42a^4, 7a^5 42a?

Algebra
Find the following. Assume that variables can represent any real number. SqRt(a+8)^2= 8a^2?

(sqrt3+5 sqrt6)(sqrt3-5 sqrt6) DRWLS-Just take the difference of the squares of the two terms, sqrt 3 and 5 sqrt6. Then you will have the answer. It will be a negative integer. 3sqrt is 9 6sq rt is 36 I add 5 to one and subtract 5 from the other? 50 and 55, then I am supposed ...

Algebra Sq Rt
3sqrt is 9 6sq rt is 36 I add 5 to one and subtract 5 from the other? 50 and 55, then I am supposed to multiply? 50x55=2750? Or is the difference -5?

Algebra Sq Rt
This looks like a trick question (sqrt3+5 sqrt6)(sqrt3-5 sqrt6) Do I sq 3 or do I add 3 and 5 first? I think I have to do the same to both sides.
