Answer:
<em><u>4(10+9) - 40 + 36</u></em>
<em><u>9(5+2) - 45 + 18</u></em>
<em><u>3(12+7) - 36 + 21</u></em>
Answer:
f(fx) = 64x + 81
Step-by-step explanation:
f(x) = 8x + 9
f(fx) = 8(8x+9) + 9
= 64x + 72 + 9
= 64x + 81
(Correct me if i am wrong)
Answer:
The area of the shaded region= 37.68
Step-by-step explanation:
Area of the outer circle= 2* 3.14* 36 (Area of the circle=2
r)
=113.04
Area of the inner circle=2*3.14* 12
=75.36
Area of the shaded region= Area of the outer circle- Area of the inner circle
= 113.04- 75.36
=37.68
A = bh
A = (22)(18)
A = 396 m²
A = ¹/₂h(b₁ + b₂)
A = ¹/₂(8)(16 + 12)
A = ¹/₂(8)(28)
A = ¹/₂(224)
A = 112 cm²
P = 2l + 2w
20 = 2l + 2(4)
20 = 2l + 8
- 8 - 8
12 = 2l
2 2
6 = l
C = 2πr
C = 2(3.14)(8)
C = 2(25.12)
C = 50.24 in
A = πr²
A = (3.14)(3)²
A = (3.14)(9)
A = 28.26 m²
