Answer:
(x-4)(x+4)
Step-by-step explanation:
This is a special case. Eventually, it will be helpful to memorize these, but for now, this special case is (a-b)(a+b)=(a^2)-(b^2). In this case, a=x and b=4 because the square root of 16 is 4. Plug in your numbers and then you have: (x-4)(x+4) which is your answer!
I hope this helped! :)

Answer:
g(g(x)) = 4x + 9
Step-by-step explanation:
To obtain g(g(x)) substitute x = g(x) into g(x) , that is
g(g(x))
= g(2x + 3)
= 2(2x + 3) + 3 ← distribute parenthesis
= 4x + 6 + 3 ← collect like terms
= 4x + 9

Complete Question
A contestant in a game show has 9,000 points. The contestant answers the next question incorrectly and loses 750 points. Does the word "lose" suggest a positive integer or a negative integer? What integer represents a loss of 750 points?
a) Positive, + 750
b) Positive , - 750
c) Negative , +750
d) Negative , - 750
Answer:
d) Negative , - 750
Step-by-step explanation:
We are told in the question that the contestant has 9000 points
Then he loses 750 points.
This means that the 750 points would be deducted from the 9000 points he the contestant has already.
The word lose is a negative and it carries the Subtraction (-) sign,
hence, lose suggests a negative integer which is given as:
-750

The answer is A it only has 1 line of symmetry.
Step-by-step explanation:
A line of symmetry is a line that cuts a shape exactly in half.
This means that if you were to fold the shape along the line, both halves would match exactly. Equally, if you were to place a mirror along the line, the shape would remain unchanged.
However, for this shape you can only fold the shape once (vertically) to have an exact match; making the answer the first option.

What is Newton's second law of motion ?
Newton's second law of motion states that time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it
Given
Force = 48 N
Acceleration = 0.35 m/s^2
Mass = ?
according to Newton's second law of motion,
Force = mass * volume
mass = force / volume
= 48 / 0.35
= 137.14 ≈137 kg
The mass of the refrigerator is b) 137 kg

Bikash got discount of Rs 3000 with 13 percent discount rate to buy a TV set what was the MP of set
Answer:
discount amt. =rs 3000
dis% = 13%
MP = ?
we know,
discount amt. = dis% ×MP

or, 3000 = 13÷ 100 × MP
or, 3000 × 100 = 13 × MP
or, 300000÷ 13 = MP
or, 23076.9 = MP
