To solve, you start with distributive property and multiply 7 by n and 3 for
7n-21<-63 the you get the 7n alone by adding 21 to -63 and the 21 for 7n<-42. now you divide 7 by itself and 42 for n<-6
Answer:
£389.4 (interest earned, not total amount of money in account)
Step-by-step explanation:
Interest = principal * rate * time (years)
I = 885 * 0.0275 * 16
I = 398.4
The percentage increase in the area of a rectangle is 44% if each of its sides is increased by 20%.
<h3>What is a rectangle?</h3>
It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
New length = (120x/100) m
New breadth = (120y/100) m
New area = (6x/5 × 6y/5) m²
The difference between the original area = xy
new area 36xy/25
Percentage increase = (11xy/25 1/xy x 100)
= 44%
Thus, the percentage increase in the area of a rectangle is 44% if each of its sides is increased by 20%.

Answer:
A. 40
Step-by-step explanation:
In such a geometry the measure of the angle is the average of the measures of the intercepted arcs.
∠1 = ∠3 = (50° +30°)/2 = 40°
