For this specific equation we have to use something called factor by grouping to simplify the equation. This is done by using like terms. To began ill break the equation into two groups.
i) (1)12x^3-60x^2
(2) 4x-20
ii) Now we look for like terms and simplify
(1) 12x^2(x-5)
(2) 4(x-5)
iii) Now we put them back as they were in the equation
12x^2(x-5) + 4(x-5)
iv) Now the x-5 factors out
we have (x-5)(12x^2+4)
Lasty, we simplify it to:
(x-5)4(3x^2+1) or 4(3x2 + 1)(x-5)
The last choice given in the answer bank.
Hope this helps, good luck.
Answer:
Volume = 108 ft³
Step-by-step explanation:
Volume of a sphere is given by the expression,
V = 
Here, r = Radius of the sphere
From the picture attached,
Radius of the sphere = 3 ft
By substituting the value of r in the expression,
Volume = 
= 36π
= 36×3
= 108 ft³
Answer:
x=2, y=5
Step-by-step explanation:
Answer:
(7,11) solution is correct
Let's sub for x = 7 and y = 11 in the first equation
Y = 2x - 3
11 = 2(7) - 3
11 = 14 - 3
11 = 11
Making the answer correct
