Split the shape into two shapes

A square

Area = L x H = 20 x 21 = 240 cm2

A right angle triangle


Area of right angle triangle = L x H divided by 2

20 x 21 = 240 divided by 2 = 120 cm2

Add both areas

240 + 120 = 360 cm2

10-d = -34-5d solve this equation
algol13
<h3><u>Explanation</u></h3>
  • Given the equation.

10 - d =  - 34 - 5d

  • Solve the equation for d-term.

Because we cannot subtract or add up constants and variables, we simply move the same variable term to the same side and constant term to the same constant side.

10 + 34 =  - 5d + d \\ 44 =  - 4d \\  \frac{44}{ - 4}  = d \\  - 11 = d

  • Answer Check

Substitute d = -11 in the equation.

10 - ( - 11) =  - 34 - 5( - 11) \\ 10 + 11 =  - 34 + 55 \\ 21 = 21

The equation is true for d = -11.

<h3><u>Answer</u></h3>

<u>\large \boxed{d =  - 11}</u>

Jana ran the first 3 and a half miles of a 5 mile race in 1 3rd of an hour. what was her average rate, in mph, for the first par
Lisa [10]

Answer:

always try to draw a diagram first

Step-by-step explanation:

Jana ran The first 3.5 miles in 1/3 of an hour. remember the problem tells us that we want our answer in miles per hour or mph. so we have to set up our problem so that our units match in the end. The diagram above shows 3.5 mi over 1/3 hour. so we must divide 3.5 miles by 1/3 hour

note:

3 \frac{1}{2} mi =  \frac{7mi}{2}

therefore

\frac{7mi}{2}  \:  \div  \:  \frac{1hr}{3}  =

\frac{7mi}{2}  \times  \frac{3}{1hr}  =  \frac{21mi}{2hr}  = 10 \frac{1}{2}  \frac{mi}{hr}

Simplify (92 – 3 × 7) ÷ (7 – 3)
Illusion [34]

Answer:

17 3/4

Step-by-step explanation:

Equation: (92 - 3*7)/(7-3)

PEMDAS so parenthesis first. Then multiplication so 7 times 3 is 21. For 7 minus 3 would be four. Like this: (92-21)/4

Subtraction: 71/4

Answer: 17 3/4

Find the area of the polygon.
zalisa [80]

Answer:

A=128\ cm^2

Step-by-step explanation:

we know that

The area of the polygon is equal to the area of a square plus the area of four congruent triangles

so

A=b^2+4[\frac{1}{2}(b)(h)]

where

b=8\ cm\\h=4\ cm

substitute

A=8^2+4[\frac{1}{2}(8)(4)]

A=64+64=128\ cm^2
