Answer:
x=4
Step-by-step explanation:
28-16=12 / 3 = 4
B = (2x+3)(4x^2-6x+9)-2(4^3-1)
B = 8x^3-99

Answer:
raise = $0.76
new wage = $10.26 per hour
Step-by-step explanation:
8% in decimal form = 8/100 = 0.08
To find 8% of 9.50: 0.08 x 9.50 = 0.76
Therefore, the housekeeper's raise = $0.76
To calculate the amount she now earns after the raise, add the 8% rise to the initial value:
0.76 + 9.50 = $10.26

Answer:
308[cos(45) + isin(45)]
Step-by-step explanation:
z1×z2:
Modulus: r1 × r2
= 7×44 = 308
Argument: theta1 + theta2
= -70 + 115 = 45
z1z2 = 308[cos(45) + isin(45)]
Or
z1z2 = 154sqrt(2) + (i)154sqrt(2)
sqrt: square root
