Answer:
True
Step-by-step explanation:
G(p+4)=3(p+4)^2+2(p+4)+27
=3p^2+24p+48+2p+8+27
=3p^2+26p+83
Answer:
Step-by-step explanation:
x = total number of students
1500 + 367x = 16,600
367x = 16,600 - 1500
367x = 15100
x = 15100 / 367
x = 41.14.......rounds to 41 students <==
this only works if the port fees and taxes that the city gave them are included in the money the class raised
Answer:
8.5cm
Step-by-step explanation:
convert 3.4metres to cm that is by multiplying by 100
3.4×100=340cm
1rep 40
?rep 340
that is 340/40
=8.5cm
Rearrange the equation by writing
x² + x - 90 = 0
x² + x = 90
x² + x + 1/4 = 90 + 1/4
Recall that (a + b)² = a² + 2ab + b². Then
x² + 2 • x/2 + (1/2)² = 361/4
(x + 1/2)² = 361/4
x + 1/2 = ± √(361/4)
x = -1/2 ± 19/2
x = 9 or x = -10
