1 is a factor of 24, but not a multiple of 4
2 is a factor of 24, but not a multiple of 4
3 is a factor of 24, but not a multiple of 4
6 is a factor of 24, but not a multiple of 4
Fist plug in 7 in to the X values like so 12 (3 (7) +5 (7)) then solve in side the parenthesis 3×7 =21 and 5×7=35 then add them 35+21=56 and then you are left with 12(56) or 12×56= 672
Use parentheses for M and N

一一一一一
remove parentheses

一一一一一
add like terms
-6 = 5(7) + b
-6 = 35 + b
-41 = b
y = 5x - 41 is the point slope form.
Step-by-step explanation:
(a) n² + 3
First term = 1² + 3 = 4
Second term = 2² + 3 = 7
Third term = 3² + 3 = 12
Fourth term = 4² + 3 = 19
10th term = 10² + 3 = 103
(b) 2n²
First term = 2(1)² = 2
Second term = 2(2)² = 8
Third term = 2(3)² = 18
Fourth term = 2(4)²= 32
10th term = 2(10)² = 200
Hence, this is the required solution.
