Answer:
n= -12
Step-by-step explanation:
- 2n/3 + 7=15 Subtract 7 from both sides and move all terms containing
-7 = -7 n to the right
- 2n/3 = 8 multiply both sides of equation by - 3/2
-3/2 x (-2n/3) = -3/2 x 8
n= -3/2 x 8 cancel the common factor of 3
n= -12

Answer:
Step-by-step explanation: 50r - 6= 82r-70
Add 50r to 82r which equals to 132 r
Now add the the 70 to the left side so -6+70 should equal 76.
Now it should look like this 76=132r
To get the value of r you have to divide 76/132 on both sides of the equation and your answer should be 0.57=r
Answer:
(2n + 1)(n + 3) + (2n + 1)(n - 2)
= (2n + 1)(n + 3 + n - 2)
= (2n + 1)2n + 1)
= 4n² + 4n + 1
= 2(2n² + 2n) + 1
can see 2(2n² + 2n) is a multiple of 2 but 1 isnt a multiple of 2
=> 2(2n² + 2n) + 1 is not a multiple of 2
=> (2n + 1)(n + 3) + (2n + 1)(n - 2) is not a multiple of 2
