We know that the area of a rectangle is equal to the width multiplied by the length. So in this case the algebraic expression is (x+5)*(3x+10). You get 3x^2 +10x +15x +50= 3x^2 +25x +50.
Answer:
50
Step-by-step explanation:
∠J=2×∠L=50
When two angles are subtended by the same arc, the angle at the centre of a circle is twice the angle at the circumference
