Answer:
626.7 
Step-by-step explanation:
Consider the figure as a circle with radius 7.5 and a rectangle with width 30 and length 15.
CIRCLE
A = pi*r*r = pi*7.5*7.5 = 56.25pi =176.7
RECTANGLE
A = l*w = 15*30 = 450
176.7 + 450 = 626.7 
2n+8 maybe try that i dont get the question..kinda confusing

Answer:
input x = - 7
Step-by-step explanation:
A is modelled as y = 5x - 4
B is modelled as y = 3x + 8
We require output of A three times the output of B , then
5x - 4 = 3(3x + 8) ← distribute
5x - 4 = 9x + 24 ( subtract 9x from both sides )
- 4x - 4 = 24 ( add 4 to both sides )
- 4x = 28 ( divide both sides by - 4 )
x = - 7 ← input
Hey there!
If we use pemdas:
P - Parentheses
E - Exponents
M - Multiplicatiom
D - Division
A - Addition
S - Subtractiom
We know we have to evaluate the exponent first. Two to the rid power is equal to 8. Therefore, we have:
2 - 4/2 + 8
Next, we do the division. -4/2 = -2, so we have:
2-2 + 8 = 0 + 8 = 8
Hope this helps!
