The area of the rectangular field is 468cm².
Step-by-step explanation:
If, length is 18cm; width is unknown( let x represent width). Then,
<u>Perimeter of a rectangle</u>= Length + Width+ Length + Width
88= 18 + x + 18 + x
88= 36 + 2x
88-36 =2x
52= 2x
52/2=2x/2
26=x
•x=26cm
<em>The</em><em> </em><em>width</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>rectangle</em><em> </em><em>is</em><em> </em><em>2</em><em>6</em><em>c</em><em>m</em><em>.</em>
<u>Area of a rectangle</u>= Length × Width
=18cm×26cm
= 468cm².
Answer:
x = π/2, 7π/6, or 11π/6
Step-by-step explanation:
sin² x − cos² x − sin x = 0
Use Pythagorean identity to write cosine in terms of sine.
sin² x − (1 − sin² x) − sin x = 0
sin² x − 1 + sin² x − sin x = 0
2 sin² x − sin x − 1 = 0
Factor:
(2 sin x + 1) (sin x − 1) = 0
Solve:
sin x = -1/2 or 1
x = π/2, 7π/6, or 11π/6

Answer:
25 points
Step-by-step explanation:
2/5 of 2125 =2 ×2125 :5 =4250 :5 =850 points Liam
2125 +850 =2975 points (Liam and Lianna)
3000 - 2975 =25 points they need
