Answer:
B.
Step-by-step explanation:
2x²(3x³ - 9x +27)
= 6x^5 - 18x³ + 54
Positive number are on the right of the zero on the number line.
The answer is 80! If you ever see any angle like that where it’s just two lines (I don’t know how to explain it/forgot what it’s called) it will be the same as the other angle.
Answer:
9x² − 12x + 4
Step-by-step explanation:
A perfect square trinomial:
a² + 2ab +b²= (a + b)²
a² - 2ab +b²= (a - b)²
9x² − 12x + 4 = (3x)² - 2*(3x)*2 + 2² = (3x - 2)²
36b² − 24b + 16
16x² − 24x − 9
4a² − 10a − 25
Answer: $25
Step-by-step explanation:
t = t-shirts
3t + 15 = 90
3t = 75
t = 25
