Answer:
5
10
4
7
Step-by-step explanation:
Apply the value of x into the expressions:
3(5) - 10 = 15 - 10
= 5
5² - 15 = 25 - 15
= 10
5(5) - 21 = 25 - 21
= 4
5 + 10 - 8 = 15 - 8
= 7
3x-10:
3(5)-10 = 15-10= 5
The answer is 5
X^2 -15:
(5)^2 -15 = 25-15 = 10
The answer is 10
5x-21:
5(5)-21=25-21=4
The answer is 4
x+10-8:
(5)+10-8=15-8=7
The answer is 7
