Answer:

Quick Answer it is A

Step-by-step explanation:

You have developed an angle bisector.

That means that JKM = LKM

B: is incorrect. The 1/2 should go on the angle on the left, not the one where it is

C: is incorrect. 1/2 of the given angle cannot be the same as the bisected angle.

D: is wrong. A bisected angle can't be twice as big as the given angle before it is bisected.

Answer:

See below.

Step-by-step explanation:

I'm assuming these questions are about the Midline Theorem (segment AL joins the midpoints of the non-parallel sides.

♦ The midline's length is the average of the lengths of the top and bottom parallel sides.

$AL=\frac{OR+CE}{2}$

Use this equation and substitute values given in each problem, then solve for the missing information.

1. AL = x, CE = 9, OR = 5

$x=\frac{9+5}{2}=7$

2. AL = m - 4, CE = 15, OR = 17

$m-4=\frac{15+17}{2}=16\\\\m-4=16\\\\\\m=20\\\\AL=20-4=16$

3. OR = y + 5, AL = 15, CE = 18

$15=\frac{(y+5)+18}{2}\\\\15=\frac{y+23}{2}\\\\30=y+23\\\\7=y\\\\OR = 7+5=12$

Which equation is quadratic in form?

Drupady [299]

we know that

A quadratic equation is a polynomial with an order of two. Its general form is

$ax^{2} + bx + c = 0$

case a) $6(x + 2)^{2} + 8x + 2 + 1 = 0$

$6(x + 2)^{2} + 8x + 2 + 1 = 0 \\ 6(x^{2} +4x+4)+8x+3=0\\ 6x^{2} +24x+24+8x+3=0\\ 6x^{2} +32x+27=0\\\\ a=6\\ b=32\\ c=27$

The case a) is a quadratic equation

case b) $6x^{4} + 7x^{2} - 3 = 0$

The case b) is a grade $4$ polynomial

case c) $5x^{6} + x^{4} + 12 = 0$

The case c) is a grade $6$ polynomial

case d) $x^{9} + x^{3} - 10 = 0$

The case d) is a grade $9$ polynomial

therefore

the answer is

$6(x + 2)^{2} + 8x + 2 + 1 = 0$

Write how many hundred thousands, ten thousands, and thousands there are in the numbers of acres of Land Big Bend National Park

sveta [45]

To solve this problem, we must remember our place values. 100,000 represents hundred thousands, 10,000 represents ten thousands, and 1,000 represents thousands similarly to how 100 represents hundreds, 10 represents tens, and 1 represents ones. Using this knowledge, we know that the number 8 is in the hundred thousands place, the number 0 is in the ten thousands place, and the number 1 is in the thousands place.

This means that there are 8 hundred thousands, 0 ten thousands, and 1 thousand in the number of acres of land the National Park owns.

Hope this helps!

Solve the following system of equations graphically.

Flauer [41]

Answer:

{(2, 1)}

Step-by-step explanation:

The graph shows the only solution to be the point (2, 1). Hence the solution set will be a set containing one element—that point:

{(2, 1)}
