Answer:
Step-by-step explanation:
4+3+5= 12 marbles
3/12 * 2/11 = 6/132 = 4.5%
6x-14+12x+8 that is the answer
First, 0.0004853 is < 1, so we need to multiply the number by 10 to a negative power if it's greater than 1 (if that makes sense i cant describe it better)
So, b and c is incorrect.
10 to the power of negative 4 = 0.0001, and 4.853 x 0.0001 = 0.0004853 (true), so answer is a
Answer:
Step-by-step explanation:
1) the two members of the expression has 4x in common, so we can rewrite it as: 4x(3x-2)
2) we have to find two numbers that multipied give -36 and that added up give 5
the two number are 9 and -4
we can rewrite the expression as : (x+9)(x-4)
3) we have to solve the associated equation
3x^2+10x+8 = 0
Δ/4 = 25-24 = 1
x1 = (-5+1)/3 = -4/3
x2 = (-5-1)/3 = -2
now we can rewrite the expression as
3(x+4/3)(x+2) = (3x+4)(x+2)
<span> 2 (a+4)+6a=48
2a + 8 + 6a = 48
8a = 40
a = 5</span>
