Step-by-step explanation:
(ax + b)² = a²x² + 2abx + b²
In this case, a = 1, so:
14 = 2b
b = 7
(x + 7)² = x² + 14x + 49
What if this !? Tricky answer : explanation
Answer:
Domain : all real numbers
Range: All numbers greater than 2
Step-by-step explanation:
The shark. (Haha, I'm sorry.)
There are no restrictions on the x. X can be any real number.
The range, however, does have restrictions. The range has to be a number greater than 0.
Why?
Because any number that you put in for x won't make the range less than 2. If you put in zero for x, the range is 2.
Answer:
138
Step-by-step explanation:
p(x) = 3x^4 + 2x^3 − 4x^2 + 21
Let x = 2
p(2) = 3*(2)^4 + 2*(2)^3 − 4*(2)^2 + 21
= 3*16+2*8-4*4+21
=48+16-16+21
= 69
This is per girl
There are 2 girls
2 * 69
138
The correct answer choice is
