5m-8=3m+8
(Plus the '8' to both sides)
5m=3m+16
(Subtract '3m' from both sides)
2m=16
(Divide by 2)
m=8

Step-by-step explanation:
Perimeter:
We have two straight, congruent sides from the square that are 24 cm, and two semi-circles (or one whole circle).
24 + 24 + 1/2(24pi) + 1/2(24pi)
48 + 12pi + 12pi
48 + 24pi cm
Area:
We have a semi-circle and a square that is missing a semi-circle. Let's find the area of the square minus the semi-circle, then add the additional semi-circle.
Square = 576
Missing semi-circle = 144pi / 2 = 72pi
Semi-circle = 144pi / 2 = 72pi
576 - 72pi + 72pi
576 cm^2
Hope this helps!
Answer:
a)
Step-by-step explanation:
Cost function = revenue function - profit function
= -0.3x² + 150x - [-0.5x² + 250x - 300]
= -0.3x² + 150x + 0.5x² - 250x +300
= -0.3x² + 0.5x² + 150x - 250x + 300 {Combine like terms}
= 0.2x² - 100x + 300
