Trying to factor by splitting the middle term
2.1 Factoring 12x2-10x+5
The first term is, 12x2 its coefficient is 12 .
The middle term is, -10x its coefficient is -10 .
The last term, "the constant", is +5
Step-1 : Multiply the coefficient of the first term by the constant 12 • 5 = 60
Step-2 : Find two factors of 60 whose sum equals the coefficient of the middle term, which is -10 .
Area of the 2 end triangles plus area of the 2 rectangular sides plus the area of the bottom rectangle
2 end Triangles
=2x(1/2bh)
=2x1/2x4x6
=24
2 side rectangles
=2(lw)
=2x5x13
=130
Bottom rectangle
=6x13
=78
Total = 24 + 130 + 78 =232
Answer: (-2,-4)
Step-by-step explanation:
To find the midpoint between two points we need to find the mean average between the x and the y .
Since we know the midpoint will have to represent the missing coordinates by the variables.
Solve for x to find the x coordinate by first multiplying both sides by -4.
-6 + x = -8 Add -6 to both sides
+6 +6
x = -2
The x coordinate of the B is -2 now we need to find the y coordinate.
Multiply both sides by 2
4 + y = 0 Subtract 4 from both sides
-4 -4
y = -4
The y coordinate is -4 so the coordinates will be (-2,-4)
Answer:
A cylinder's volume is π r² h, and its surface area is 2π r h + 2π r².
38,000 - 18,000 = 20,000 ft
20,0000 ÷ 600
=33.3
= 33 minutes 20 seconds
