Answer:
Step-by-step explanation:
4x + 7 + 2x + 5 = 180
6x + 12 = 180
6x = 168
x = 28
4(28) + 7= 112 + 7= 119
2(28) + 5 = 56 + 5= 61
Division operation of function:
Example:
The answer is $19.80
Mass m=25 g
Volume V=1.29 cm³
density D=M/V
=25/1.29
≈19.38
≈19 g/cm³
48x^2-48x+12
3(area of square)
3(w^2)
3((4x-2)^2)
3(16x^2-16x+4)
