Answer:
Step-by-step explanation:
產品 1 14 20 13
產品 2 15 11 18
產品 3 12 15 16
180=(3x+25)+2x. Soooooo X=31
Since there are two halves in a whole, you can times each number by 2 to get the number of halves it has.
12*2=24
10*2=20
13*2=26
15*2=30
8*2=16
5*2=10
Answer:
Step-by-step explanation:
f(x + 1) = 8(x + 1) + 1 = 8x + 8 + 1 = 8x + 9
Rewrite and factor 9 and 21;
3•3+3•7= 3(3+7)
GCF for 9 and 21 is 3
