Answer:
x = 3
Step-by-step explanation:
4x+2 = x+11
Subtract x from each side
4x+2-x = x+11-x
3x+2 =11
Subtract 2 from each side
3x+2-2 =11-2
3x = 9
Divide by 3
3x/3 =9/3
x = 3

Answer:
Four
Step-by-step explanation:
Let's expand and see how many nonzero terms:
⇒ (x+4)(2x²+3x+9)-3(x³-2x²+7x)=
⇒ 2x³ + 3x² + 9x + 8x² + 12 + 36 - 3x³ + 6 x² - 21 x=
⇒ - x³ + 17x² - 12x + 12
As we see the expression has four nonzero terms
Odd integers are 2 apart
they are n, n+2, n+4
the sum is 75
n+n+2+n+4=75
3n+6=75
minus 6 both sides
3n=69
divide both sides by 3
n=23
n+2=25
n+4=27
the integers are 23,25,27
Answer:
1. no. 2.no
Step-by-step explanation:
1.
= (5\3) × (1/1-x)
but 8-8x = 8(1-x)
2. 2(6-3x) = 12-6x =6(2-x)
2(3x) + x= 6x +x = 7x
