Answer: m=8
Step-by-step explanation:
5m-8=3m+8
Move the variable to the left hand side and change its sign; move the constant to the right hand sign and change it's sign
5m-3m=8+8
Collect like terms
2m=16
Divide both sides by 2
2m/2=16/2
m=8

Answer:
24.0 square feet
Step-by-step explanation:
The area of the sector is given by ...
A = (1/2)r²θ . . . . . where θ is the angle in radians
The area of the circle is the same, with θ=2π, so is ...
A = πr²
__
In this problem, the area of the sector is ...
A = (1/2)(9 ft)²(24π/180) = 27π/5 ft² ≈ 16.9646 ft²
The area of the circle is ...
A = π(1.5 ft)² = 9π/4 ft² ≈ 7.0686 ft²
Then the total area of the exclamation point is ...
16.9646 +7.0686 ≈ 24.0 . . . ft²
The area is about 24.0 square feet.
