Answer: Her account would earn $17.5
Step-by-step explanation: The earning on a given amount with simple interest can be computed as follows;
Interest = PRT/100
Where P is the principal (initial amount), R is the rate of interest and T is the number of years. The formula now becomes,
Interest = (50 x 3.5 x 10)/100
Interest = 1750/100
Interest = 17.5
Therefore, in 10 years her account would have earned $17.5
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
