Step-by-step explanation:
BODMAS
1.multiply 20 by 2
2.20 ×2
3. 40+22+40+20+43=123
It's a. 3.
because
3+6x=21

Answer:
72°
Step-by-step explanation:
The lengths 25 cm and 8 cm are the sides of the rectangle.
See the attached diagram of rectangle ABCD.
Now, let us assume the diagonal AC makes x° angle with the shorter side BC i.e.∠ BCA = x°
So, using trigonometry we can write
⇒ degrees ≈ 72 degrees {Rounded to nearest degree} (Answer)
Answer:
see explanation
Step-by-step explanation:
Substitute n = 1 into each of the expressions
8n + 6
= 8(1) + 6
= 8 + 6
= 14
2(4n + 3)
= 2(4(1) + 3)
= 2(4 + 3)
= 2(7)
= 14
14n
= 14(1)
= 14
