Answer:14
Step-by-step explanation:
He takes 2 a week so 2 times 7 is 14
Step-by-step explanation:
2x + 7 = 27 OR 3 + 3x = 30.
2x = 27 - 7 OR 3x = 30 - 3
2x = 20 OR 3x = 27
x = 20/2 OR x = 27/3
x = 10 OR x = 9

Answer:
A=132
Step-by-step explanation:
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=3·10+4·10+5·10+1
2·﹣34+2·(3·4)2+2·(3·5)2﹣44+2·(4·5)2﹣54=132
