Answer:

Part a) The value of x is 10

Part b) The perimeter of triangle JKL is $79\ units$

Step-by-step explanation:

Part a) Find the value of x

we know that

The Triangle Proportionality Theorem, states that if a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally

$(3x-5)/(3x-5+10)=(28-8)/(28)\n \n(3x-5)/(3x+5)=(20)/(28) \n \n(3x-5)(28)=(3x+5)(20) \n \n84x-140=60x+100\n \n84x-60x=140+100\n \n24x=240\n \nx=10$

Part b) we know that

The perimeter of triangle JKL is equal to

$P=JK+KL+JL$

substitute the values

$P=(3x+5)+28+16=3x+49$

substitute the value of x

$P=3(10)+49=79\ units$

B. Standard Form
Please help

Answers

First, let's find the slope of the line using the formula $(y_2 - y_1)/(x_2 - x_1)$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are points on the line.

The equation for the slope of this line would be:

$((7)/(5) - (6)/(5))/(-(3)/(5) - (2)/(5)) = ((1)/(5))/(-1) = -(1)/(5)$

Now, let's find use the point-slope equation to find an equation for our line, which is $(y - y_1) = m(x - x_1)$ , where $(x_1, y_1)$ is a point on the line and $m$ is the slope. The point-slope equation for our line would be:

$(y - (6)/(5)) = -(1)/(5)(x - (2)/(5))$

$y - (6)/(5) = -(1)/(5)x + (2)/(25)$

$y = -(1)/(5)x + (32)/(25)$

The slope-intercept form of the line would be y = -x/5 + 32/25.

Now, we can use operations to convert this equation into standard form:

$25y = -5x + 32$

$5x + 25y = 32$

The standard form of the line would be 5x + 25y = 32.
