Hope dis helps ya
21 x 9 = 9 x 21 is the commutative property.
9^ ? 3^2 + 7^2
81 ? 9 + 49
81 > 58
c^ > a^2 + b^2
answer is obtuse triangle
Answer:
A = 22 degrees

Answer:
1. -3
2. 7
3. -2
4. 3
Step-by-step explanation:
1. idk
2. 3.2 move 3b over to get 3.2-3b-4.7=-3.3 move 4.7 over to get
3.2b-3b=4.7-3.3 now 3.2b-3b=.2b and 4.7-3.3=1.4 .2b/.2=b 1.4/.2=7 so b=7
3. 4.6y-y+4=y-1.2 now switch the 4 and the y to read 4.6y-2y=-4-1.2
2.6y=-5.2 divide both sides by 2.6 to get y=-2
4. 7.5c-2.5c+8=-7 move 8 to other side to get 7.5c-2.5c=-8-7
5c=-15 divide both sides by 5 getting c=3
