(a-b)(2a+4b) = 2a² - 2ab + 4ab - 4b² = 2a² + 2ab - 4b²
Answer:
h=2A/a+b
Step-by-step explanation:
Distribute the terms
Divide by two
Isolate h
That would be the steps
A. The ratio of soccer balls to all balls are 4:25
All the balls combined are 50 balls
8 of the balls are soccer balls so that makes the ration 8:50
In the simplest form it is 4:25 since you can't divide 4 or 8 by 50, you can use 2
and you get 4:25 as your answer
So it is A.
The answer is (C)- The next generation will weigh less than the parent generation, closer to 5 kg.
Step-by-step explanation:
Answer: x > 6, x < -8
Subtract 4 from both sides.
−3∣x+1∣<−17−4
Then simplify -17 - 4 to -21.
−3∣x+1∣<−21
Divide both sides by −3.
|x + 1| > -21/-3
Two negatives make a positive.
|x + 1| > 21/3
simplify 21/3 to 7
Break down the problem into these 2 equations.
x + 1 > 7
-(x + 1) > 7
Solve the 1st equation: x + 1 > 7
x > 6
Solve the 2nd equation: -(x + 1) > 7
x < -8
last collect all solutions
x > 6, x < -8
