<span>If 7 dancers were at a dance and 46 more came in and h left and there was 13 dancers left how many was h
</span>- h is 70.
(-5a)(-3a ²)
=
15a³
-5 x -3 = 15 ( negative times negative = positive)
a x a² = a³ ( when multiplying exponents, you add the exponents together )
Answer:
Step-by-step explanation:
a). Total surface area of cylinder is defined by sum of curved surface area and surface area of the top and bottom.
Total surface area = 2πrh + 2πr²
Skateboarders use a half pipe structure which are not closed at the ends.
Therefore, curved surface of the half pipe = 
= πrh
b). If r = 2.5 m and h = 9 m,
Curved surface area of the half pipe = π(2.5)(9)
= 70.69 m²
≈ 71 m²
(3x+8)(2x + 6)
6x^2+18x+16x+42
6x^2+34x+42
using the foil method, you can expand the given expression. It is already in simplified form with the given (3x+8)(2x+6)
Answer:
