Keep these rules in mind:
- (a + b)² = a² + 2ab + b²
- (a - b)² = a² - 2ab + b²
- (a + b)(a - b) = a² - b²
Firstly, solve the exponent and multiplication:
Next, combine like terms:
Next, subtract 4x² on both sides:
Next, subtract 25 on both sides:
Lastly, divide both sides by -20.5. And since you are dividing by a <u>negative</u>, flip the inequality sign:
<u>Your answer is x > 2.</u>
Each brother should get 4 slices. 12 slices divided by 3 brothers equals 4 slices each.
Answer: D: y<4x-2
Step-by-step explanation:
4x - 2 > y:
The line is dotted and shading is below the line since y is less than 4x-2.
Answer:
1/9^15
Step-by-step explanation:
Answer:
No, a triangle cannot have sides with the given lengths. That is because the sum of any two of the sides must be greater than the third side. In this case, the sum of 5 and 5 is less than the third side, 15.
Step-by-step explanation:
z = 5
3 (5) = 15
Triangle sides: 5, 5, 15
5 + 5 = 10
10 < 15
i hope this helps and is right! p.s. i really need brainliest :)
