Answer:
36 units squared
Step-by-step explanation:
Since this is kind of a weird shape, we can split it into two smaller shapes, a triangle, and a rectangle.
The rectangle is 6 units wide, and 4 units long. Multiply the length and width to get 24 units squared.
The triangle has a base of 6 and a height of 4, so multiply the base and height, then divide by 2. 6 times 4 is 24 and that divided by 2 is 12.
Finally add the two areas together. 24+12=36 units squared.
Answer:
A) x greater than or equal to −3
Step-by-step explanation:
We have the following inequality:
7 − 9x − (x + 12) ≤ 25
Solving the inequation, we have:
7 − 9x − x - 12 ≤ 25
-10x ≤ 30
-x ≤ 3
x≥-3
Therefore the result is option A) x greater than or equal to −3
Answer:
Step-by-step explanation:
Let the speed of the car is x, then the speed of motorcycle is x + 20
The distance = 120 km
<u>Time:</u>
- 120/x = 120/(x + 20) + 1
- 120(x + 20) = 120x + x(x +20)
- 120x + 2400 = 120x + x² + 20x
- x² + 20x = 2400
- x² + 2*10x + 10² = 2500
- (x + 10)² = 50²
- x + 10 = 50
- x = 40
Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h
