The area of the triangle could be determined by multiplying the length and the width. Since, we are given the area and the length, to find the width, you divide the area by the length:
w = A ÷ l
w = (x2 - 2x - 15) ÷ (x+3)
What do you have to multiply to (x+3) to yield x2 - 2x - 15? That would be x - 5. Since the sum of -5 and 3 = -2 (middle term) and the their product is -15 (last term).
Hence, the width is (x-5).
Answer:
Step-by-step explanation:
(((22•5ax2) + 25ax) + 15a) - 5 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
20ax2 + 25ax + 15a - 5 =
5 • (4ax2 + 5ax + 3a - 1)
Equation at the end of step 3 :
5 • (4ax2 + 5ax + 3a - 1) = 0
Step 4 :
Equations which are never true :
4.1 Solve : 5 = 0
The differential equation that has the given slope is: dy/dx = -xy.
<h3>How to find the differential equation that models the situation?</h3>
We have to look at the slope, given in the graph of the solution of the differential equation, and represented by dy/dx. From the graph, we have that:
- In quadrants I and III, in which x and y have the same signal, the differential equation is decreasing, hence the slope is negative.
- In quadrants II and IV, in which x and y have different signals the differential equation is increasing, hence the slope is positive.
The differential equation that is negative when x and y have the same signals and positive when they do not have is given by the following option:
dy/dx = -xy.

Given inequality
=> −2(x+1)≥3x+8
=>

now multiply with - on both sides.
As we know now sign will change
=> 5x >_ -10
Now divide by 5 on both sides
=> x >_ -2
