Group and factor/undistribute
(x^2y^3-2y^3)+(-2x^2+4)
(y^3)(x^2-2)+(-2)(x^2-2)
see the (x^2-2) is common term so undistribute
(x^2-2)(y^2-2)
last one
My answer is C
because
x-12=-3
x=-3+12
x=9
Answer:
12
Step-by-step explanation:
Let the total number of donuts in the pack be x.
Amy = 2/3x
Anna = 1/4x
David = 1
x - 2/3x - 1/4x = 1
Find common denominators for 2/3 and 1/4
The common denominator is 12
2/3 * 4/4 = 8/12
1/4 * 3/3 = 3/12
x - 8/12x - 3/12x = 1
x - 11/12x = 1
1/12x = 1
x = 12
You can always check
Amy = 8
Anna = 3
So David must equal to 1
Hope this helps :)
Have an awesome day!
Answer: This hard behind question
Step-by-step explanation:
Answer:
4 × 10¹⁰ > 2 × 10⁵
Step-by-step explanation:
Given that,
Two numbers in scientific notation.
First number: 4 × 10¹⁰
Second number: 2 × 10⁵
To compare scientific notation number.
First check the exponent of 10
If exponent is larger then number becomes larger.
First number exponent is 10 and second number exponent if 5
10 > 5
Therefore,
4 × 10¹⁰ > 2 × 10⁵
