The answer is 136 because 3*17 is the length and the perimeter is 51+51+17+17

the answer is 136.

17*3=51

51*2=102

17*2=34

102+34=136

$\\ \rm\longmapsto 2^{4x+4}=64^{x+2}$

$\\ \rm\longmapsto 2^{4x+4}=(2^6)^{x+2}$

$\\ \rm\longmapsto 2^{4x+4}=2^{6(x+2)}$

$\\ \rm\longmapsto 4x+4=6(x+2)$

$\\ \rm\longmapsto 4x+4=6x+12$

$\\ \rm\longmapsto 4-12=6x-4x$

$\\ \rm\longmapsto -8=2x$

$\\ \rm\longmapsto x=\dfrac{-8}{2}$

$\\ \rm\longmapsto x=-4$

make a hypothesis about the sum of the interior angles of any trangle. Explain why your hypothesis works for all triangles

lakkis [162]

Answer:

The sum of the three angles of any triangle will always be 180 degrees because when all three angles are put together, they form a straight line.

Pleeeeese help me as fast as you can!!!

Answer:

A. $y=3x-10$

C. $y+6=3(x-15)$

Step-by-step explanation:

Given:

The given line is $6x+18y=5$

Express this in slope-intercept form $y=mx+b$ , where m is the slope and b is the y-intercept.

$6x+18y=5\\18y=-6x+5\\y=-\frac{6}{18}x+\frac{5}{18}\\y=-\frac{1}{3}x+\frac{5}{18}$

Therefore, the slope of the line is $m=-\frac{1}{3}$ .

Now, for perpendicular lines, the product of their slopes is equal to -1.

Let us find the slopes of each lines.

Option A:

$y=3x-10$

On comparing with the slope-intercept form, we get slope as $m_{A}=3$ .

Now, $m\times m_{A}=-\frac{1}{3}\times 3=-1$ . So, option A is perpendicular to the given line.

Option B:

For lines of the form $x=a$ , where, a is a constant, the slope is undefined. So, option B is incorrect.

Option C:

On comparing with the slope-point form, we get slope as $m_{C}=3$ .

Now, $m\times m_{C}=-\frac{1}{3}\times 3=-1$ . So, option C is perpendicular to the given line.

Option D:

$3x+9y=8\\9y=-3x+8\\y=-\frac{3}{9}x+\frac{8}{9}\\y=-\frac{1}{3}x+\frac{8}{9}$

On comparing with the slope-intercept form, we get slope as $m_{D}=-\frac{1}{3}$ .

Now, $m\times m_{D}=-\frac{1}{3}\times -\frac{1}{3}=\frac{1}{9}$ . So, option D is not perpendicular to the given line.
