Add the ratios together: 3+7=10. The ratio means that there are 3/10×40=12 orange seashells and 7/10×40=28 pink seashells.
<h3>
Answer: 168 square cm</h3>
==============================================
Work Shown:
- L = 2 = length
- W = 6 = width
- H = 9 = height
The order of length, width and height doesn't matter
SA = surface area of rectangular prism
SA = 2*(LW + LH + WH)
SA = 2*(2*6 + 2*9 + 6*9)
SA = 2*(12 + 18 + 54)
SA = 2*(30+54)
SA = 2*(84)
SA = 168 square cm
F(x) = | 4x - 1 | .....when f(x) = 7
7 = | 4x - 1 |
4x - 1 = 7 -(4x - 1) = 7
4x = 7 + 1 -4x + 1 = 7
4x = 8 -4x = 7 - 1
x = 8/4 -4x = 6
x = 2 x = -6/4
x = - 3/2
solutions are x = -3/2, 2
