Answer:
Shorter leg = 20 cm.
Longer leg = 21cm.
Hypotenuse = 29 cm
Step-by-step explanation:
Let the shorter leg be x cm long
Then longer leg = x + 1 and hypotenuse = x + 9 cm long
So by Pythagoras:
x^2 + (x + 1)^2 = (x + 9)^2
0 = x^2 + 18x + 81 - x^2 - (x^2 + 2x + 1)
x^2 + 18x + 81 - x^2 - x^2 - 2x - 1 = 0
-x^2 + 16x + 80 = 0
x^2 - 16x - 80 = 0
(x - 20)(x + 4) = 0
So x = 20 (we ignore the negative root).
So longer leg = 20 + 1 and hypotenuse = 20 + 9.
<span>f(x)=10x+8
</span>
<span>g(x)=1x+4 = x+4
(f+g)(x) = f(x) + g(x) = 10x+8+x+4 = 11x + 12
</span>
<span>(f+g)(3)= 11(3) + 12 = 33 + 12 = 45
hope that helps

Answer:
A. 8 students
B. Because 24% of 24 is 5.76
Step-by-step explanation:
A: The ratio of students is 2:5, that means for every 7 students from her class, 2 of them are in the show.
28/7 is 4, so there are 2(4) = 8 students in the talent show.
B: 24(24%) = 24(0.24) = 5.76. The question says 'exactly' 24%. We can't have 0.76 of a person, so we can't have 'exactly' 24%
