Answer:
√61
Step-by-step explanation:
using Pythagorean theorem,
h²+b²=hy²
h²+b²=hy²4²+2²=hy²
h²+b²=hy²4²+2²=hy²16+4=20
h²+b²=hy²4²+2²=hy²16+4=20hy²=20
therefore in radical form, Hy=√20
<em>with </em><em>the </em><em>same </em><em>theorem;</em>
h²= hy²-b²
b² is initially given as (√20)²
hy² is given as 9²
h²=9²-(√20)²
h²=81-20
h²=61
h=√61
Answer:
There are no like terms hence they stay the same
Step-by-step explanation:
x + (y + 9)
There are no like terms
=x+y+9
(x + y) + 9
There are no like terms
=x+y+9
Am sure it’s the 1 first option

My answer is 1/6. Here's How I worked it out:
11/21 / 22/7 is the same as or = to 11/21 * 7/22 which = 77/462 and then divide both the numerator and denominator by 77 and you get 1/6. (In other words simplify 77/462). Hope this helped :)
