Answer:
s(21) = 101.
Step-by-step explanation:
Just substitute n = 21 in the general form:
s(21) = 5(21) - 4
= 105 - 4
= 101. (answer)>
Formula- Area = L • W
So...
Length = 18 + 3
Width = 18 + 3
Since you’re adding 18 + 3 for Length AND Width, you’re going to get a sum of 21 for each.
Length = 21
Width = 21
Now you’re gonna want to multiply 21 by itself.
21 • 21 = 21 + 420 = ?
Which leaves you with the final sum of...
Area = 441 yds.
Answer:
y=0.5x
Step-by-step explanation:
i took the test on edg
- <em>area of the whole circle = r^2 times pi</em>
- radius is 10 units
- thus, the whole circle's area is 100pi square units.
...and this shape is exactly one quarter, one-fourth, of the whole circle. <em>Why? because of the shape's right angle and radius. (when you multiply 90 times 4, it will equal 360 degrees, which is the angle of a whole circle.)</em>
so 100pi divided by 4 equals 25pi square units of the shape.
ANSWER:
25 pi square units
(or in decimals: multiply 25 by 3.14 which would be 78.5 square units)
