Answer:
106
Step-by-step explanation:
Substitute x = 3 into f(x) and evaluate , that is
f(3)
= 10(3)² + 6(3) - 2 = 10(9) + 18 - 2 = 90 + 18 - 2 = 106
Answer:
Perimeter of Square Q = 49
Step-by-step explanation:
given:
sides P:Q = 2:7
side length of P = 3.5.
First, determine length of side Q by using the ratio
The perimeter is 4 times the length of the side
So, Perimeter of square Q = 4 *(7*3.5)/2 = 49
