Answer:
x = -3 or x = -5/3
Step-by-step explanation:
Solve for x over the real numbers:
(x + 3) (3 x + 5) = 0
Split into two equations:
x + 3 = 0 or 3 x + 5 = 0
Subtract 3 from both sides:
x = -3 or 3 x + 5 = 0
Subtract 5 from both sides:
x = -3 or 3 x = -5
Divide both sides by 3:
Answer: x = -3 or x = -5/3
Answer:
r = 152/55
Step-by-step explanation:
122 - 44r = - 30 + 11r
122 - 44r - 11r = - 30
- 44r - 11r = - 30 - 122
- 55r = - 30 - 122
- 55r = - 152

1) The line will need to be vertical down the point of x, meaning draw a line down point x. Perpendicular lines look similar to t’s
2.) Same thing, just draw a line through point O and the line. They should look similar to t’s
Hope this helped!! I understand math can get really hard, soon it’ll all be over :)
Answer:
(Square, Right Triangle)
18 meters²
Step-by-step explanation:
You can divide the shape into a square and right triangle, see the attachment :)
The area of the square is the length times the width. So,
3 · 3 = 9
The area of the square is 9 m².
The triangle's area is the base times the height divided by 2. So,
6 · 3 = 18
18 / 2 = 9
The triangle has an area of 9 m².
Add these together.
9 + 9 = 18
The area is 18 meters².
