Answer:
The three numbers are -1 6/7, -5 4/7, and 5 3/7
Step-by-step explanation:
The three numbers can be represented as...
x, 3x+11, and 3x
x+3x+3x+11=-2
7x+11=-2
7x=-13
x= - 1 6/7
3x= -5 4/7
3x+11= 5 3/7
Answer:
x=0, -5/3
Step-by-step explanation:
For all triangles, the angle sum is 180°, therfore we can add all the angles up to solve x
54 + 55 + x + 74 =180
183 + x =180
X = 180 - 183
X = - 3 °
Don't worry, negative result is normal and possible.
Answer:
3 units
Step-by-step explanation:
So if we want to know how high the spring board is, this will need to be the time at which the diver is still at the top of the board, in this case t = 0 seconds.
So we will need to find h(0)
- h(0) = 5(0)² + 10(0) + 3 = 0 + 0 + 3 = 3
