Answer:
b. (x-3) / (x+1)
c. x/(x+5)
Step-by-step explanation:
b. (x+2)(x-3) / (x+1)(x+2)
c. x(x - 5) / (x + 5 ( x - 5)
= x / x+5
7+ 30 or 31 or 28 or 29 not sure that's what ur asking for
9514 1404 393
Answer:
Step-by-step explanation:
a) You go about this by using the given equation.
Left + Right = Total
JK + KL = JL
(2x -3) + 11 = 4x
8 = 2x . . . . . simplify, subtract 2x
4 = x . . . . . . divide by 2
__
b) JL = 4x = 4·4
JL = 16
We can assume that the point the ladder creates with the ground and building is a triangle. You can use the Pythagorean theorem to solve this.
A^2 + B^2 = C^2
The ladder is C, and the building can act as A or B, so for the purpose of this explanation, I’ll make it A.
11^2 + B^2 = 14^2
Figure out the squares
121 + B^2 = 196
Subtract 121 from both sides
B^2 = 75
Square root B^2 and 75
B = 5 root3
Considering the hang time equation, it is found that Player 1 jumped 0.68 feet higher than Player 2.
<h3>What is the hang time equation?</h3>
The hang-time of the ball for a player of jump h is given by:

The expression can be simplified as:

For a player that has a hang time of 0.9s, the jump is found as follows:




h = 3.24 feet.
For a player that has a hang time of 0.8s, the jump is found as follows:




h = 2.56 feet.
The difference is given by:
3.24 - 2.56 = 0.68 feet.
