3 because u keep the number Wich is 8 the same but change the three to four
Answer:you solve on each sides like normal then your equation will come out as “not a solution”
Step-by-step explanation:
13=-7
Answer:
4x(x - 1)
Step-by-step explanation:
Factor the numerator and denominator
64
- 64x ← factor out 64x from both terms
= 64x(
- 1) ← difference of squares
= 64x(x² - 1)(x² + 1) ← x² - 1 is also a difference of squares
= 64x(x - 1)(x + 1)(x² + 1)
---------------------------------
(8x² + 8)(2x + 2) ← factor out 8 and 2 from each factor
= 8(x² + 1) × 2(x + 1)
= 16(x² + 1)(x + 1)
Then expression can be written as
← cancel (x² + 1) and (x + 1) on numerator/ denominator
= 
← cancel common factor 16 on numerator/ denominator
= 4x(x - 1)
Answer:
he stayed 8 hours and 35 minutes
Step-by-step explanation:
15 -7 =8
45-10=35
(3x − 5) − (4x + 6)
Pretend that there is a 1 in front of the first bracket.
Pretend that there is a -1 in front of the second bracket.
Multiply the first bracket by 1
(1)(3x)=3x, (1)(-5)=-5
Multiply the second bracket by -1
(-1)(4)=-4, (-1)(6)=-6
3x-5-4x-6
3x-4x-5-6 ( combine like terms)
-x-11
Answer: -x-11 or -11-x
