ANSWER
The function is quadratic

Quadratic term:
- 6 {x}^{2}

Linear term:
- 17x
Constant term:
- 12

EXPLANATION

The given function is

y = (3x + 4)( - 2x - 3)

Let us expand to obtain,

y = - 6 {x}^{2} - 9x- 8x - 12

We simplify to get,

The highest degree of the function is 2.

y = - 6 {x}^{2} - 17x - 12

Therefore the function is quadratic and the quadratic term is
- 6{x}^{2}
The linear term is,

- 17x

and the constant term is

- 12

Y=(3x+4)(-2x-3)=-6x^2-4x-9x-12=-6x^2-13x-12.
It is a quadratic function because it has x in power 2 (x^2)

On analyzing the question we can say that the angle ∠JKM of the triangle ΔJKL would be 42 as line MK bisects ∠JKL into ∠JKM & ∠MKL.

From the question it follows that line MK bisects angle ∠JKL into ∠JKM & ∠MKL where M is the point in the interior of ∠JKL.

Therefore, as we have given  m∠JKL = 84 & m∠MKL  = 42

and we have to find m∠JKM , we will simply write the equation as follow

m∠JKL = m∠JKM + m∠MKL

Inserting values we get,

84 = m∠JKM + 42

m∠JKM = 42

Hence, angle m∠JKM  of the triangle ΔJKL is  42.

Given: JK tangent, KH=16, HE=12 Find: JK.
Y_Kistochka [10]

Answer: JK=8

Step-by-step explanation:

You can observe in the figure that JK is a tangent and KH is a secant and both intersect at the point K. Then, according to the Intersecting secant-tangent Theorem:

JK^2=KE*KH

You know that:

KH=KE+HE

Then KE is:

KE=KH-HE

KE=16-12

KE=4

Now you can substitute the value of KE and the value of KH into  JK^2=KE*KH and solve for JK. Then the result is:

JK^2=4*16\\JK^2=64\\JK=\sqrt{64}\\JK=8

A carpenter is framing a wall that is 8 feet high and 15 feet long. If the carpenter wants to be sure that the sides of the wall
Ad libitum [116K]

If you cut the rectangle (the wall) diagonally, you get two congruent triangles. The measurements of the sides of one the triangles is 8, 15 and x. There is a pythagorean triples 8, 15, 17 so x has to be 17. if you dont know the triple you can do a^2 + b^2 = c^2         8^2 + 15^2 = c^2     c = 17

the diagonal of wall should be 17
