Answer:
7.7
Step-by-step explanation:
The area of the wall is 4 * 2 = 8.
The radius of each clock is 0.3 / 2 = 0.15.
The area of all 4 circles is 4 * (πr²) = 4 * 3.14 * 0.15² = 0.3.
8 - 0.3 = 7.7
Answer:
6.9
Step-by-step explanation:
Total area of the wall is 4 x 2 = 8
Area for a circle is π x radius^2
Therefore total area of 4 clocks = 4 (π x 0.3^2)
Which is: 1.13...
Now we take away this answer from the area of the wall:
8 - 1.13... = 6.9 (1 d.p)

Answer:
x = -7
Step-by-step explanation:
2x+2-x+5=0
x+2+5=0
x+7=0
x = -7
So the answer is -7
Perimeter = sum of all sides
32 = 2(x+2) + 2(7)
32 = 2x+4 + 14
32 = 2x+18
14 = 2x
/2 /2
7 = x
