Area of rectangle = Length x width, Area of triangle - (1/2) base x height
Surface Area is the sum of the area of all of the faces.

Your picture has 5 faces:
1) rectangle on the left
2) square in the middle
3) rectangle on the right
4 & 5) 2 congruent (identical) right triangles

Area of face #1: 5 x 4 = 20
Area of face #2: 4 x 4 = 16
Area of face #3: 3 x 4 = 12
Area of face #4: (1/2) x 3 x 4 = 6
Area of face #5: (1/2) x 3 x 4 = 6
Sum of the Area of the faces: 60

Answer: Surface Area of the figure is 60 units²

Volume = Length x width x height
             =     5      x    4    x     3
             = 60 units³

Answer: Volume of the figure is 60 units³

Surface area is not the volume

Surface area=60units^2

2 triangles(4x3)/2  = 6 units each=12 units

1 square 4x4=16units

1 rectangle 4x3=12

1 rectangle 4x5=20

6+6+16+12+20=60 units^2

Answer please cuz I'm very confused

5x + 3y = - 53

the equation of a line in ' slope- intercept form ' is y = mx + c

where m is the slope and c the y-intercept

rearrange 3x - 5y = - 15 into this form to obtain m → (subtract 3x from both sides)

- 5y = - 3x - 15 → divide all terms by - 5 )

y = \frac{3}{5} x + 3 → in slope-intercept form with m = \frac{3}{5}

given a line with slope m then the slope m₁ of a line perpendicular to it is

m₁ = - \frac{1}{m} = - 1 ÷ \frac{3}{5} = - \frac{5}{3}

partial equation is y = - \frac{5}{3} x + c

to find c substitute ( - 7, - 6) into the partial equation

- 6 = \frac{35}{3} + c ⇒ c = - 6 - \frac{35}{3} = - \frac{53}{3}

y = - \frac{5}{3} x - \frac{53}{3} → in slope intercept form

multiply all terms by 3

3y = - 5x - 53 → ( add 5x to both sides )

5x + 3y = - 53 → in standard form

What are the solutions to the equation x² + 16x + 14 = 0?
poizon [28]

Answer:

-8+5√2 and -8-5√2

Step-by-step explanation:

Given the expression x² + 16x + 14 = 0

USing the general formulas

x = -16±√16²-4(14)/2

x = -16±√256-56/2

x = -16±√200/2

x = -16±10√2/2

x = -8±5√2

Hence the required solutions are -8+5√2 and -8-5√2
