Answer:
v=11/5 or v=2.2
Step-by-step explanation:
The wording of this question is a little confusing but if it says what I think it does (5/3v+4=8-1/3) then this is the answer.
Answer:
The trestle meets ground level at 0.9 units and 9.1 units
Step-by-step explanation:
∵ -x² + 10x - 8 = 0 ⇒ × (-1)
∴ x² - 10x + 8 = 0
∵ 10x/2 = 5x ⇒ (x) × (5) ⇒ square x is x² and square 5 is 25
By using completing square form
∴ (x² - 10x + 25) - 25 + 8 = 0
∴ (x - 5)² - 17 = 0
∴ (x - 5)² = 17 ⇒ take square root for both sides
∴ x - 5 = -√17 ⇒ x = -√17 + 5 = 0.9
∴ x - 5 = √17 ⇒ x = √17 + 5 = 9.1
∴ The trestle meets ground level at x = 0.9 and x = 9.1
I might be wrong-
The commutative property holds for subtraction only.<span>When the numbers being subtracted are the same. It is sometimes true.</span><span>

Answer: ( x − 4 ) ( x + 36 )
Step-by-step explanation:
Use the sum-product pattern
^2 + 3
2
− 1
4
4
^2 + 36
− 4
− 1
4
4
Common factor from the two pairs
^2 + 3
6
− 4
− 1
4
4
( + 3
6 ) − 4 ( + 3
6 )
x ( x + 36 ) - 4 ( x + 36 )
Rewrite in factored form
( + 3
6 ) − 4 ( + 3
6 )
( x - 4 ) ( x + 36 )
Solution
( − 4 ) ( + 3
6 )
