Answer:

{84mm}^{2}

Step-by-step explanation:

Area of square= l×l

Area of square= 6mm × 6mn

Area if square = 36 mm²

Area of triangle 1= ½b ×h

Area of triangle 1= ½ (6mm)(8mm)

Area of triangle 1 = 24 mm²

Area of triangle 2 is the same as area of traingle 1 because they have the same base and hight

: . area of triangles is 48mm²

Area of the figure= Area of square + Area of triangles

A of figure = 36+48

A of figure = 84 mm²

Option 2

Use trapezium formula

Area of trapezium= (a+b)/2 * h

a=6 mm (base)

b=8+6=14 mm (Base)

h= 6mm (height)

area \: of \: trapezium = ( \frac{6 + 14}{2} )(6) \\  = 60mm ^{2}

Therefore the area of triangle= 24mm² as calculated in option 1

Area of the figure= Area of trapezium +Area of triangle

Area of figure = 60+24

= 84 mm²

How do you solve 5/x=x-4
alexandr402 [8]
\frac{5}{x}=x-4\\
x\not=0\\
5=x^2-4x\\
x^2-4x-5=0\\
x^2+x-5x-5=0\\
x(x+1)-5(x+1)=0\\
(x-5)(x+1)=0\\
x=5 \vee x=-1

a rocket is scheduled to launch from a command center in 3.75 hours. what time is it now if launch time is 11:20am. i need to kn
gtnhenbr [62]

The equation would be 3.75+t=11.2 so:

3.75+t=11.2

3.75+t-3.75=11.2-3.75

t=7.45, which is 7:35.
