Answer:
21
Step-by-step explanation:
product of 3 number= 1197
1st number= 3
2nd number= 19
3rd number= let,X
Now,
3*19*X= 1197
or, 57*X= 1197
or, X= 1197/57
X= 21
Answer:
x = 3 and x = 4
Step-by-step explanation:
3x - 4 + 4x - 8 = x^2
7x -12 = x^2
x^2 - 7x + 12 = 0
(-4)*(-3) = 12 and (-4)+(-3) = -7
(x-3)(x-4) = 0
x - 3 = 0. x = 3
x - 4 = 0. x = 4
Answer:
Write the problem as a mathematical expression.
b(12)=4.8b
Move 12 to the left of b.
12b=4.8b
Move all terms containing b to the left side of the equation.
7.2b=0
Divide each term by 7.2 and simplify.
b=0
