Answer:
1 & 2 = Right Triangles
3 & 4 = Not Right Triangles
Step-by-step explanation:
Solved Using Pythagorean Theorem:
1)
= 225
= 225
2)
= 1521
= 1521
3)
= 776
= 784
4)
= 244
= 256
R=i/pt
i=16731.12-16100=631.12
R=631.12/16,100×1
R=0.0392*100=3.92%
Answer:
Step-by-step explanation:
It is A and C
X= 65
Explanation:
Simplify both sides of equations
3(x)+7)(2)+8=440
6x+42+8=440 (Distribute)
(6x)+(42+8)=440
(Combine Like Terms)
Step 2: subtract 50 from each side
6x+50−50=440-50 6x=390
Step 3: Divide both sides by 6
6x/6 = 390/6
