It would have to be number 2) x-3
IF IT EQUALS 0
1. find two number that multiplied to 48 and adds to 14, which are 6 and 8.
2. substitute the new numbers in with x to get x^2 + 6x + 8x + 48.
3. factor out the x and the 8 to get x(x+6)+8(x+6).
4. x = -6, x = -8
IF IT DOES NOT EQUAL 0
then (x+6)*(x+8) is your answer.
Answer:
5.76
Step-by-step explanation:
Easy way to work with percentage is to take the decimal and move it over one to the left and that will give you 10%.
Since you 38.40 move the decimal over one to the left and you'll get 3.84. That is 10%, but since you need 15% divide 3.84 by two to get 5%- that is 1.92.
3.84 (10%) + 1.92 (5%) = 5.76 (15%)
Answer:
48
Step-by-step explanation:
5*12=60
4*12=48
Answer:
x = 6
Step-by-step explanation:
2/(x-2) = 5/(4+x) - set up the ratios of similar sides
2(4 + x) = 5(x - 2) - cross multiply to solve
8 + 2x = 5x - 10 - simplify
18 = 3x - simplify to get x on one side of the equation
6 = x - divide both sides of the equation by 3 to isolate x
