Answer:
Step-by-step explanation:
we know that
The area of the composite figure is equal to the area of a right triangle plus the area of rectangle
see the attached figure to better understand the problem
step 1
Find the area of the right triangle
we know that
The area of triangle is
where
substitute
step 2
Find the area of rectangle
The area of rectangle is equal to
where
substitute
step 3
Find the area of the composite figure
Adds the areas
Find the square root of the number since the area of a square is side^2The answer would be 88sqrt(ab) or 11sqrt(a)2sqrt(b)4
Answer:
Step-by-step explanation:
First, we can write:
x
=
1
.
¯¯¯¯
21
Next, we can multiply each side by
100
giving:
100
x
=
121
.
¯¯¯¯
21
Then we can subtract each side of the first equation from each side of the second equation giving:
100
x
−
x
=
121
.
¯¯¯¯
21
−
1
.

We can now solve for
x
as follows:
100
x
−
1
x
=
(
121
+
0
.

x
=
