Answer:

x = - y-12/5+4k

Step-by-step explanation:

<u>Solve 12-5x-4kx=y for x</u>

12-5x-4kx = y for x

substract 12 from both side

-5x-4kx = y-12

Factor of -5x-4kx = -x(5+4k)

-x(5+4k) = y-12

Solve for x

-x = y-12/(5+4k)

Therefore x = - y-12/5+4k

How is the formula for the area of a triangle related to the formula for the area of a parallelogram?

Andreas93 [3]

Area of a triangle is A= 1/2 b x h and Area of a parallelogram is A=b x h. So I would say the area of a triangle is half of the area of a parallelogram. Or a parallelogram is double the area of a triangle.

Two corresponding sides of two similar triangles are 3cm and 5cm. The area of the first triangle is 12cm2. What is the area of t

love history [14]

Answer:

$33\dfrac{1}{3}\ cm^2$

Step-by-step explanation:

If two corresponding sides of two similar triangles are 3cm and 5cm, then the scale factor is

$k=\dfrac{a_1}{a_2}=\dfrac{3}{5}.$

Two similar triangles have their area proportional with the scale factor of $k^2.$

Hence,

$\dfrac{A_1}{A_2}=k^2,\\ \\\dfrac{12}{A_2}=\left(\dfrac{3}{5}\right)^2,\\ \\\dfrac{12}{A_2}=\dfrac{9}{25},\\ \\A_2=\dfrac{12\cdot 25}{9}=\dfrac{100}{3}=33\dfrac{1}{3}\ cm^2.$
