5*20=100, the answer would be 100 dots
Answer: 13:15
26:30
39:45
52:60
Step-by-step explanation:
rounded part is a semicircle so the area for that is the area of a circle ÷ 2
so
area of the rectangle + (area of the circle ÷ 2) = answer
24 * 14 = 336 = area of the rectangle
14 ÷ 2 = r
(pi * 7^2) ÷ 2
(pi * 49) ÷ 2 = 153.86 ÷ 2 = 76.93 = area of semicircle
336 + 76.93 = 412.93 ft^2 = answer
Answer:
The solution set is 
Step-by-step explanation:
we have
Solve for x
Subtract 
both sides
Divide by 
both sides
The solution is the interval------->
All real numbers greater than 
F(2a)=35
35=(2a)^2-1
35=4a^2-1
minus 35 from both sidse
0=4a^2-36
facor out 4
0=4(a^2-9)
factor differece of 2 perfect squares
0=4(a-3)(a+3)
set to zero
a-3=0
a=3
a+3=0
a=-3
a=-3 or 3
