14 (286/20 = 14,3) you just need to remove the decimal and you can see how many times it can enter
Answer:
4 (X + 1) (x + 2)
Step-by-step explanation:
metal plate: 5x²+12x+10
Circle removed: x²+2
Remain after circle removal: (5x²+12x+10) -(x²+2) = 4x² + 12x + 8
4x² + 12x + 8 = 4 (x² + 3x + 2) = 4 (X + 1) (x + 2)

Answer:
R32.15
Step-by-step explanation:
Let x and y represent the original price of a loaf of bread and a liter of drink, respectively. The two relations given by the problem statement are ...
10x +12y = 138.90
10(1.2x) +12(1.1y) = 159.54
Multiplying the first equation by 1.2 and subtracting the second gives ...
1.2(10x +12y) -(10(1.2x) +12(1.1y)) = 1.2(138.90) -(159.54)
1.2y = 7.14 . . . . collect terms
y = 5.95 . . . . . divide by 1.2
The value of x can be found from the first equation.
10x + 12(5.95) = 138.90
10x = 67.50 . . . . . . . . . . . subtract 71.40
x = 6.75 . . . . divide by 10
Then the value of 3x+2y is ...
3(6.75) +2(5.95) = 32.15
The original price of 3 loaves and 2 liters is R31.15.
Answer:
<h2>
V = 360π in³</h2>
Step-by-step explanation:
the formula for the volume of a cone of base radius r and height h is:
V = (1/3)(πr²)(h). Here, r = 6 in and h = 30 in. Then,
V = (1/3)(π)(6 in)²(30 in), or
= (1/3)π(36 in²)(30 in), or
V = 360π in³
