Answer:
x=4.0625 cm
Step-by-step explanation:
The Pythagorean theorem states that the square of the hypotenuse of a right triangle equals the sum of the squares of the two legs.
Not knowing which is the hypotenuse, lets assume that (x+5)cm is the hypotenuse:
(x+5)^2= 9^2+(x-3)^2
(x^2+10x+25)=81+(x^2-6x+9)
x^2+10x+25=81+x^2-6x+9
16x=65
x=4.0625
Checking:
(4.0625+5)^2=9^2+(4.0625-3)^2
82.1289=82.1289
Answer:
49
Step-by-step explanation:
with a square all sides are equal so if one side is 7 the other is 7 so you would do 7 * 7

<h3>
Answer: 10/16</h3>
===========================================================
Explanation:
All of the answer choices are fractions with 16 as the denominator. We can compare the numerators to see which is largest. In that case it's 10, so 10/16 is largest.
-----
You can use a calculator to find the decimal value of each fraction
4/16 = 0.25
3/16 = 0.1875
8/16 = 0.5
10/16 = 0.625
and we can see that 0.625 is largest so 10/16 is largest
