Answer:
1. 125
2. 25
3. 40
4. 39
First question:
(15-10)^2 + (15-5)^2
parentheses first to get 5^2 + (15-5)^2
exponents next to get 25 + (15-5)^2
parentheses again 25 + 10^2
exponents again 25 + 100 = 125
Second question:
simplify the exponents (3 *3) + (4 * 4) + (2 * 2) to get 9 + 16 + 4 = 29
Third question:
simplify in the parentheses 6 1/7 - 1/7 = 6
divide 60 by 6 to get 10
multiply 10 by 4 to get 40!
Fourth question:
simplify the fractions to get 1/3 + 8/3 = 3
multiply the 3 by 13 to get 39

Answer:
Step-by-step explanation:
The GCF (greatest common factor) of 24 and 30 is 6.
30-30/6=25
25 students in the class
24% of 25 is 6
6 girls in the class
T=-50 is the answer........
That increases the population of the torn by a factor of 4, which takes it from 100% to 400% of its initial population, which means an increase of 300%.
