Answer:
10x -6
Step-by-step explanation:
f(x) = 5x + 2x = 7x
g(x) = 3x - 6
f(x) + g(x) = 7x+ 3x-6
= 10x -6
Answer:
Jane has a constant rate of pay because her earnings go up by 12 every unit of time.
Answer:
If I am correct, I think the surface area is 448.
Step-by-step explanation:
First start by finding the area of all the sides
Front side. 12 x 10 = 120
2 triangle sides: 8 x 10 = 80, 80 x 2 = 160
Bottom side: 6 x 12 = 72
Back side: 8 x 12 = 96
Then add up the surface area
120 + 160 + 72 + 96 = 448
Btw I don't know if I am correct, but I think this is the way you find surface area.
2 hours she earns €16
