Answer:
B
Step-by-step explanation:
16 x² - 49 ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b), thus
16x² - 49
= (4x)² - 7²
= (4x + 7)(4x - 7) → B
Answer:
B
Step-by-step explanation:
There is no number between 16x and 49. So only think about the number being squared for 49; which is 7.
Then 49 is negative, so you must have both positive and negative signs in both parenthesis. Otherwise, positive times positive is positive, and negative times negative is also positive.
4x4 is 16. That's why you put fours in front of Xs.

It is given in the question that
The gas tank of Tyrell's truck holds 19.8 gallons. when the tank empty, Tyrrell fills it with gas that costs $3.65 per gallon.
It means cost of one gallon of gas is $3.65 .
And the tank hold 19.8 gallon . So cost of 19.8 gallon is
Therefore about $72.27 it will cost to fill the tank .

Explanation:
The reciprocal of a number is to switch the numerator and denominator. In (1/7), the numerator is 1 and the denominator is 7. A fraction is always numerator/denominator. So, when (1/7) is flipped, the fraction’s reciprocal is (7/1) which is simplified to 7.

b. What is the area of the paper that can be painted when the margin is 2 inches wide?
Answers
Answer:
a. A = x² - 36x + 288
b. If x = 2; A = 220 in²
Step-by-step explanation:
a.
In this scenario, 'x' represents the width of the border. A "uniform border" means that the border has the same width all around.
The area of the paper that can be painted does not include the border. Since the border is on the original rice paper (not added to it), you subtract 'x' from each side of the rice paper.
The area of a rectangle is A = lw (Area is length times width). Each length and width is reduced by 'x'.
If the original rice paper's area is: 24 X 12, then,
the Area that can be painted is:
A = (24 - x) (12 - x)
A polynomial in standard form means the most expanded version of an expression, ordering the terms (numbers) from greatest to least degree. (The degree of a term is the value of its exponent).
Expand the expression. Multiply the numbers from each bracket in the order FOIL (first, outside, inside last):
A = (24 - x) (12 - x)
= 288 - 24x - 12x + x² Collect like terms (-24x - 12x = -36x)
= 288 - 36x + x² Rearrange ordering greatest to least exponent value
= x² - 36x + 288 Standard form polynomial
b.
The width of the margin is the same thing as the width of the border. Since 'x' is the width of the border,
x = 2
Using either the expanded or factored equation for area of that can be painted, substitute 'x' for 2.
I will use the factored form.
A = (24 - x) (12 - x) Substitute x for 2
= (24 - 2) (12 - 2) Solve inside each bracket first by subtracting
= (22) (10) Multiply
= 220 Area that can be painted
Remember to include the units: 220 in²
Therefore if the margin is 2 inches wide, then the area that can be painted in 220 square inches.
