Answer:
b
Step-by-step explanation:
It is 12×3 = 36
4(3) = 12 and multiply with three i.e. 12×3=36
25x2 − 16
25x2 + 16
25x2 − 40x + 16
Answer:
25x^2 + 40x + 16
Step-by-step explanation:
(5x + 4)^2
= (5x + 4)*(5x + 4)
= 25x^2 + 20x + 20x + 16
= 25x^2 + 40x + 16
The answer is, in fact, A. I took the test and the answer was correct.
The Value of x=±
To find the value of X.
Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.
Assuming
a≠0...
First subtract c from both sides to get:
Divide both sides by a and transpose to get:
So x must be a square root of and we can deduce:
x=±
So, the Value of x=±
