Answer:
Scuba diver started at 2 feet above the sea level, dove down 20 feet, and rose up 8 feet
Step-by-step explanation:
The initial number is 2 which is more than 0 that means the diver did not start at a ground level but above than that.
The negative 20 denotes that he went down the sea level, to the extent of the number provided in feet.
Further, after that dive the positive number provides the height in feet covered to rise up from the down level of dive.
I choose A. 0, because the angles are complementary
Answer:
How do you find the sum of factors of a quadratic equation?
Let r and s be the factors for the quadratic equation such that x^2+Bx+C=(x−r)(x−s) where sum of factors (r+s)=−B and the product of factors rs = C r = -2 - u s = -2 + u Two numbers r and s sum up to -4 exactly when the average of the two numbers is \frac{1}{2}*-4 = -2.
How do you solve a quadratic equation?
Quadratic equations such as this one can be solved by completing the square. In order to complete the square, the equation must first be in the form x^{2}+bx=c.

Answer:
4
Step-by-step explanation:
Given that three pairs of gloves- a red pair, a blue pair, and a green pair-are in a drawer. The gloves are removed at random without returning any to the drawer.
We have to find the minimum number that must be removed in order to guarantee having a matched pair of gloves
No of different colours = 3 (red, blue, green)
Hence no of gloves that must be removed = 3+1
If 4 gloves are removed, only 3 can be of different colours 1 will have same colour as any one of the three.
So a pair of same colour would be obtained
Answer is 4
