Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.
Match each equation with its solution set.
a2 − 9a + 14 = 0
a2 + 9a + 14 = 0
a2 + 3a − 10 = 0
a2 + 5a − 14 = 0
a2 − 5a − 14 = 0
Answer: 144
Step-by-step explanation: Its probally wrong
17. Difference between -11 and 17, which is 28.
18. -189 + 56 + 64 = -69, meaning she still owes 69 dollars.
19. -528 * 4 = -2112
20. -6,660 divided by 37 = -180
Meaning it falls 180 meters down every minute.
The value of x in order for the two slats to be parallel is 6.
The measure of the indicated angle is 42°
What is an angle?
The angle is the measure of how inclined are the two surfaces, or lines with respect to each other.
For the slats to be parallel. both the given angles must be equal
So,
(3x +24)° = 7x°
Solving this expression, we get
7x -3x = 24
4x =24
x = 6°
The measure of the indicated angle is
(3x +24)° = 3x6 +24
(3x +24)° = 18+24
(3x +24)° =42°
and 7x = 7x6 =42°
Thus, the measure of the angle is 42°
