the formula is a^2 + b^2 = c^2
a and b are the legs or the length and the width
16^2 + 12^2 = 400^2
square root 400 to get 20
the answer is 20
if you need more help let me know
Answer:
<em>24 cm </em>
Step-by-step explanation:
10² + b² = 26²
b = √(26² - 10²) = √576 = <em>24 cm</em>

Answer:
11
Step-by-step explanation:
x + 2y = 24.....x = 24 - 2y
now sub 24 - 2y in for x, back into the other equation
2x + y = 9
2(24 -2y) + y = 9
48 - 4y + y = 9
-4y + y = 9 - 48
-3y = - 39
y = -39/-3
y = 13
x + 2y = 24
x + 2(13) = 24
x + 26 = 24
x = 24 - 26
x = -2
so the value of x + y = -2 + 13 = 11 <===
1. Subtract 6 from both sides now you would get..
2z=-10
Now divide each side by 2z and you get
z= -5
So the answer is -5
