the area formula is a parallelogram is equal to (Base)*(height). If the area if a parallelogram is given by the trinomial x^2-14

abruzzese [7]

Answer:

x-12

Step by step explanation:

Here it is given that the area of a parallelogram is given by base * height. And if the area is represented by ,

$\longrightarrow A = x^2-14x+24$

And the base of the parallelogram is given by,

$\longrightarrow Base = x-2$

Substituting the values in the given formula, we have;

$\longrightarrow Area = base \times height$

$\longrightarrow x^2-14x+24=h(x-2)\\$

Divide both sides by (x-2) .

$\longrightarrow h =\dfrac{x^2-14x+24}{x-2}$

Factorise the term in numerator,

$\longrightarrow h =\dfrac{x^2-12x-2x+24}{x-2}\\$

$\longrightarrow h =\dfrac{x(x-12)-2(x-12)}{x-2}\\$

$\longrightarrow h =\dfrac{(x-2)(x-12)}{x-2}$

Simplify,

$\longrightarrow \underline{\underline{ height= x-12}}$

This is the required answer!

ray buys a sweatshirt from model’s for $38. he also wants to buy socks ,s, that cost $3 per pair. how many pairs of socks,s, can

SCORPION-xisa [38]

Answer:

12 pairs of socks

Step-by-step explanation:

74-38=36

36÷3=12

You subtract 38 from 74 to find out how much money he has left after buying the sweatshirt. You then divide that number by 3 to figure out how many pairs of socks he can buy with the money he has left.

Find c in the pic below

Fiesta28 [93]

Answer:

Step-by-step explanation:

To find the angle inside the triangle (to the right side of 90 degree angle), we first have to find the adjacent angle (below it).

Angle 122 and that adjacent angle is same (parallel lines cut by transversal -- they are corresponding angles).

So that angle is 122.

The inside triangle angle (what we want) is adjacent to 122, so we can write:

Angle + 122 = 180 [straight angle/straight line is 180 degrees]

Solving for that angle, we have:

Angle = 180 - 122 = 58

Now, looking at the triangle, Side C is "opposite" of 58° and side "20" is the side that is "hypotenuse" [side opposite of 90 degree angle is hypotenuse).

Which trig ratio relates "opposite" and "hypotenuse"??

Yes, it is SIN. Thus we can write:

$Sin(58)=\frac{Opposite}{Hypotenuse}=\frac{C}{20}$
