Answer: The volume of the rectangular prism is 1562.4 cm

Step-by-step explanation:

We are given the area of 173.6 cm and a height of 9 cm. We also know that the formula for area if lw, meaning we can substitute the area for lw in the volume formula. V= (173.6 cm) (9 cm) =1562.4 cm

Please help ASAP 40 PTS
umka21 [38]

Answer:

70

Step-by-step explanation:

The angle not marked in the top triangle is 40 degrees since it is an isosceles triangle.  That makes the angle opposite it in the other triangle 40 degrees since they are vertical angles and vertical angles are equal.

The bottom triangle has 3 angles that sum to 180 degrees,  The other angle not marked is also y since it is an isosceles triangle.

40 + y +y = 180

Subtract 40 from each side and combine like terms

40-40 +2y = 180-40

2y = 140

Divide by 2

2y/2 = 140/2

y = 70

1. -5(x - 2) - (x + 2) = 50
Serjik [45]

Answer:

x = - 7

Step-by-step explanation:

Given

- 5(x - 2) - (x + 2) = 50 ← distribute parenthesis on left side

- 5x + 10 - x - 2 = 50, that is

- 6x + 8 = 50 ( subtract 8 from both sides )

- 6x = 42 ( divide both sides by - 6 )

x = - 7
