Answer:
3.14 = pi
1.) R = 1.5 and A = 7.065
2.) D = 28 and A = 615.44
3.) R = 10 and A = 314
Step-by-step explanation:
R = 0.5×d
Area of circle = π×r²
W=15 subtract 80 from both sides than you divide by -2w
1)
Parameter = 10+7+3+8+4+8+3+7
Parameter = 50 ft
2)
Area = Area 1 + Area 2
Area = (10x7) + (4x8)
Area = 70 + 32
Area = 102 Sq. Feet
Answer:
x= 1
y= 3
Step-by-step explanation:
21(-2+y) +7y = 42
-42 +28y+42
28y = 42+42
28y= 84
divide both sides y= 3
x= -2+3 x=1
x= + (3-2) = 1
42=42
10=10
[ Answer ]
<u><em>5x - 5</em></u>
[ Explanation ]
<em><u>Remove Parenthesis:</u></em>
7x + 4 - (2x + 9)
- (2x + 9) : -2x - 9
= 7x + 4 -2x - 9
<u><em>Simplify:</em></u>
7x + 4 - 2x - 9 : 5x - 5
= 5x - 5
