Reika [66]3 years ago

For this case we have the following expression:

\frac {2} {5} m- \frac {4} {5} - \frac {3} {5} m =

We add similar terms:

\frac {2} {5} m- \frac {3} {5} m- \frac {4} {5} =

Different signs are subtracted and the sign of the major is placed:

\frac {2-3} {5} m- \frac {4} {5} =\\- \frac {1} {5} m- \frac {4} {5} =

The expression is simplified as:

\frac {-m-4} {5}

ANswer:

\frac {-m-4} {5}

What is the total area of the figure? Please help I’ll give brainliest!!
GalinKa [24]

Answer:

64 square inches

Step-by-step explanation:

You can split this figure into a rectangle and triangle to find the area.

A= l * w

A= 5 * 12

Area of the rectangle = 60 sq in

A= 1/2 bh

b= 12-8     = 4

h= 7-5       =2

A= 1/2 (4)(2)

Area of the triangle = 4 sq in

60 + 4 = 64 sq in

Income Statements under Absorption Costing and Variable Costing
kotykmax [81]

The estimated income statement for the month shows a loss of $840000.

<h3>How to illustrate the income statement?</h3>

The estimated income statement for the month will be:

Sales = $25,600,000

Less: Cost of goods sold

Direct materials (320000 × 15) = $4,800,000

Direct labor (320000 × 17) = $5,440,000

Variable costing (320000 × 15) = $11,200,000

Fixed manufacturing cost = $1,530,000

Total cost of goods sold = $22970000

Gross profit = $25,600,000 - $22970000 = $2,630,000

Gross profit = $2,630,000

Less:

Variable selling and administrative expense = $3200000

Fixed selling and administrative = $270000

Loss from operations = $840000

Therefore, the estimated income statement for the month shows a loss of $840000.

Triangle ABC has A(-3,6),B(2,1), and C(9,5) what the length of side AB? What the length BC what the length AC and what ABC
vovikov84 [41]

Answer:

<em>AB = 5√2</em>

<em>AC = √145</em>

<em>BC = √65</em>

Step-by-step explanation:

Using the formula for calculating the distance between two points

D = √(x2-x1)²+(y2-y1)²

For AB A(-3,6),B(2,1),

AB = √(2+3)²+(1-6)²

AB = √(5)²+(-5)²

AB = √25+25

AB =  √50

<em>AB = 5√2</em>

For AC A(-3,6) and C(9,5)

AC = √(9+3)²+(5-6)²

AC = √(12)²+(-1)²

AC = √144+1

<em>AC = √145</em>

For BC B(2,1), and C(9,5)

BC = √(9-2)²+(5-1)²

BC = √(7)²+(4)²

BC = √49+16

<em>BC = √65</em>

<em></em>

<em>Since All the sides are difference, hence triangle ABC is a scalene triangle</em>
