Answer:
3
Step-by-step explanation:
Given
- 2x - 2(3x - 7) + 4(3x - 5) - (4x - 9) ← distribute parenthesis
= - 2x - 6x + 14 + 12x - 20 - 4x + 9 ← collect like terms
= 3
3(x2+2)-3y
3((2)^2+2) - 3(2/3)
first exponents,
3(4+2) - 3(2/3)
then parenthesese
distribute 3
12 + 6 - 2
18 - 2
16

Answer:
-4x^3 - 4y^2
Step-by-step explanation:
-5y^2 + 5 - 4 - 4y^2 + 5y^2 - 4x^3 - 1
= -4x^3 -4y^2
Answer:
52.4 cm
Step-by-step explanation:
Circumference of a circle = 2πr
Radius, r = diameter / 2
= 17 cm / 2
= 8.5 cm
π = 3.14
Circumference of a circle = 2πr
= 2 × 3.14 × 8.5
= 53.38 cm
Approximately 52.4 cm
