Answer:
1.4
Step-by-step explanation:
8-1 = 7 and 7/5 = 1.4
Answer:
AD= 15
AB=30
Step-by-step explanation:
We are given that the Point D bisect the line segment AB
Hence AD = DB
AD= 4x-1
BD=9x-21
Hence
4x-1=9x-21
adding 21 on both sides and subtracting 4x from both sides
4x-4x-1+21=9x-4x-21+21
-1+21=5x
5x=20
dividing both sides by x we get
x=4
Hence
AD = 4x-1
= 4(4)-1= 16-1=15
AD= 15
AB = 2 x AD
= 2 x 15
= 30
Answer:
so the answer is the third one
11
u can reduce it into 11
Answer:
quadratic
Step-by-step explanation:
Given
x²y - 2xy - 24y ← factor out y from each term
= y(x² - 2x - 24) ← quadratic factor
To factor the quadratic
Consider the factors of the constant term ( - 24) which sum to give the coefficient of the x- term (- 2)
The factors are - 6 and + 4, since
- 6 × 4 = - 24 and - 6 + 4 = - 2, hence
x² - 2x - 24 = (x - 6)(x + 4) and
x²y - 2xy - 24y = y(x - 6)(x + 4) ← in factored form
