Answer:
(3 x)/(5 x + 2)
Step-by-step explanation:
Simplify the following:
(3 x^2)/(5 x^2 + 2 x)
Hint: | Factor common terms out of 5 x^2 + 2 x.
Factor x out of 5 x^2 + 2 x:
(3 x^2)/(x (5 x + 2))
Hint: | For all exponents, a^n a^m = a^(n + m). Apply this to (3 x^2)/(x (5 x + 2)).
Combine powers. (3 x^2)/(x (5 x + 2)) = (3 x^(2 - 1))/(5 x + 2):
(3 x^(2 - 1))/(5 x + 2)
Hint: | Evaluate 2 - 1.
2 - 1 = 1:
Answer: (3 x)/(5 x + 2)
Answer:
The required expression is
Step-by-step explanation:
Difference of two minus three = 2-3
Quotient of b divided by the difference of two minus three is
Therefore, the required expression is
Answer:
the answer is 8,000
Step-by-step explanation:
Let the number of green apples bought be x
Green apples = x
Red apples = 2x
Yellow apples = 1/3 (2x) = 2/3 x
Total = 22 apples
x + 2x + 2/3 x = 22
11/3 x = 22
11x = 66
x = 6
Green apples = x = 6
Red apples = 2x = 2(6) = 12
Yellow apples = 2/3 (2x) = 2/3 (6) = 4
Answer: Green = 6, Red = 12, Yellow = 4
Answer:
C
Step-by-step explanation:
x²+2x-15 = x²-3x+5x-15 = x(x-3)+5(x-3)=(x+5)(x-3)
or delta:
∆=2²-4*1*(-15)=4+60=64
√∆=8
x1 = (-2+8)/2 = 3
x2=(-2-8)/2=-5
and 4x+20 = 4(x+5)
The same is (x+5), so it is GCF. answer C
