Answer:

258.39 m^2

Step-by-step explanation:

Solve for the rectangle:

18 • 12= 216

Now solve for the 3 semi circles:

A = 3.14(3)^2= 28.26/2 = 14.13 •3 = 42.39

Add up the areas:

216 + 42.39 = 258.39

URGENT‼️‼️‼️‼️‼️ Is the open sentence 7x-5=2x+8 true when x=2? Justify your answer.
scZoUnD [109]

Answer:

No

Step-by-step explanation:

Substitute x = 2 into the equation and if both sides are equal then x = 2 is a solution.

left side = (7 × 2) - 5 = 14 - 5 = 9

right side = (2 × 2) + 8 = 4 + 8 = 12

left side ≠ right side

Hence x = 2 is not a solution of the equation
