Make bottom number same
ok, so remember
(a-b)(a+b)=a²+b²
so
to get from (y-x) to (y²-x²), multiply 2nd fraction by (y+x)
so multiply 2nd fraction by (y+x)/(y+x)

=

=
Sorry! I can't find one that is not equivalent to 1/3. Only equivalent.
Hope I helped!
We need to find the hypotenuse of the triangle. We can find that by using the Pythagorean theorem: a² + b² = c²
Solve with the given values of the triangle:
2² + 4² = c²
4 + 16 = c²
20 = c²
√20 = √c²
4.47 ≈ c
Find the area of the square using: A = bh
4.47 * 4.47 = 19.9809
Therefore, the area of the square is approximately 19.9809units²
Best of Luck!
Measure of angle 2 is 77. hope this helped.
Let w be the width then w+4 is the length and 2*w+2*(w+4)=4*w+8 is the expression for the perimeter. So
4*w+8>=48
4*w>=40
w>=10
