Step-by-step explanation:

(3x² + 4x - 8) - (-2x² + 4x + 2)

[3 - (-2) = 5] , [ 4 - 4 = 0] , [ (-8) - 2 = -10]

5x² + 0x - 10

(or)

5x² - 10

Answer:

  • 5x² - 6

Step-by-step explanation:

<u>Simplify</u>

  • (3x² + 4x - 8) - (-2x² + 4x + 2) =
  • 3x² + 4x - 8 + 2x² - 4x - 2 =
  • (3 + 2)x² + (4 - 4)x - (8 - 2) =
  • 5x² + 0x - 6 =
  • 5x² - 6

HELP ASAP!! Lesson 4: Perimeters and Areas of Similar Figures
ziro4ka [17]
Part 1) 
area of triangle=b*h/2
b=2.9 cm
h=9 cm
so
area=2.9*9/2-----> 13.05 cm²

the answer part 1) is 13.05 cm²

Part 2) 
area of the figure=area of rectangle+area of triangle

find the area of rectangle
area rectangle=b*h
b=12 ft
h=?
tan 45=1
tan 45=h/(22-10)----------> h/10=1-------> h=10 ft
area of rectangle=12*10-----> 120 ft²

area of triangle=b*h/2
b=10 ft
h=10 ft
area of triangle=10*10/2----> 50 ft²

area of the figure=120+50----> 170 ft²

the answer Part 2) is 170 ft²

Part 3)
<span>the area of kite is half the product of the diagonals. 
</span>Area=(d1*d2)/2
d1=5+5---> 10 ft
d2=16+8----> 24 ft
area=(10*24)/2----> 120 ft²

the answer Part 3) is 120 ft²

Part 4)
the area of rhombus is half the product of the diagonals. 
Area=(d1*d2)/2
d1=6+6---> 12 m
d2=6+6----> 12 m
area=(12*12)/2----> 72 m²

the answer part 4) is 72 m²

Part 5)

area of the figure=6*area of one triangle

area of triangle=b*h/2
b=4 cm
is an equilateral triangle
applying the Pythagoras theorem
h²=4²-2²-----> h²=12-----> h=2√3 cm

area of triangle=4*2√3/2----> 4√3 cm²

area of hexagon=6*(4√3)----> 24√3 cm²

the answer Part 5) is 24√3 cm²

The volume of a cylinder is 9080 in.³ the same height of the cylinder is 20 inches what is the radius of the cylinder express yo
insens350 [35]

Answer:

12.02 inches

Step-by-step explanation:

recall, volume of a cylinder is given by

V = πr²h

where r is the radius of the cylinder and h = the height

hence

9080 = π x r² x 20

r² = 9080 ÷ 20π = 144.513

r = √144.513 = 12.02 inches
