Step-by-step explanation:
A polynomial is a perfect square if has the form:

Its factored form is
.
We can obtain examples by taking any value of a and b.
For example:
anb
.
Thus we obtain a polynomial that is a perfect square:

Answer:
7.5* 10^8
Step-by-step explanation:
(1.5 x 10^5)(5 x 10^3)
Multiply the numbers
1.5*5=7.5
Add the exponents
10 ^(5+3) = 10^8
Put back together
7.5* 10^8
This is in scientific notation
Answer:
Step-by-step explanation:
x + y = 12 | -x = -y - 10
x + y = 12 | x = y + 10
y + 10 + y = 12 | x = y + 10
2y = 2 | x = y + 10
y = 1 | x = 1 + 10
(11, 1)
