Answer:

$\dfrac{2}{5}m-\dfrac{1}{5}$

Step-by-step explanation:

First, use the distributive property $a\cdot (b-c)=a\cdot b-a\cdot c.$ Thus,

$2\cdot \left(\dfrac{1}{5}m-\dfrac{2}{5}\right)=2\cdot \dfrac{1}{5}m-2\cdot \dfrac{2}{5}=\dfrac{2}{5}m-\dfrac{4}{5}.$

Then given expression will take look

$\dfrac{2}{5}m-\dfrac{4}{5}+\dfrac{3}{5}.$

This expression consists of three terms, one term with m and two terms without m. Combine terms without m:

$-\dfrac{4}{5}+\dfrac{3}{5}=-\dfrac{1}{5}.$

Therefore, an equivalent expression is

$\dfrac{2}{5}m-\dfrac{1}{5}.$

Write the equation of a line Parallel to the given line and passes through points (-4, -3); (2, 3). Hints find the slope by usin

julia-pushkina [17]

First, we obtain the gradient (slope) of the first parallel line

$\text{gradient, m}_1\text{ = }\frac{y_2-y_1}{x_2-x_1}\text{ = }\frac{3-(-3)}{2-(-4)}=\frac{6}{6}\text{ = 1}$

Recall that since both lines are parallel, we have that,

$m_1=m_2$

Thus

$m_2\text{ = 1}$

Hence, we can find the equation of the parallel line given that it passes through the points (-4, -3)

Using

$\begin{gathered} y\text{ = mx + c} \\ \text{where m = m}_2\text{ = 1} \\ \text{and x = -4 , y = -3, we have} \\ -3\text{ = 1(-4) + c} \\ -3\text{ = -4 + c} \\ 4\text{ - 3 = c} \\ c\text{ = 1} \\ \text{Thus, the equation of the line is y = (1)x + 1} \\ y\text{ = x + 1} \end{gathered}$

The perimeter of a rectangle is

e-lub [12.9K]

P = 2(L + W)

510 = 2(L + W) ...divide both sides by 2

510/2 = L + W

255 = L + W

3/5(255) = 765/5 = 153 cm <== length

2/5(255) = 510/5 = 102 cm <== width
