Answer:
11
3Step-by-step explanation:
Given
3(x - 1)² + 2x - 7 ← substitute x = 3 into the expression
= 3(3 - 1)² + 2(3) - 7
= 3(2)² + 6 - 7
= 3(4) - 1
= 12 - 1
= 11
r = 25+b
n = 3b
n+r+b=435
3b+25+b+b=435
5b+25=435
5b=210
b=42
r = 25+42 = 67
n = 3(42) = 126
144 degrees Fahrenheit.
you had to multiply 16*9=144
