Step-by-step explanation:
10×10+24×24= third side ×third side
third side ×third side =100+576
third side × third side=676
third side=√676
third side=26

Write down some equations that express what you know.
A = 2*30 + 3x
K = 1*30 + 5x
A+K = 210
Substitute the expression for A in the A+K=210 expression
2*30 +3x + K = 210
Now substitute the expression for for K
2*30 + 3x + 1*30 + 5x = 210
Multiply and combine terms
60 + 3x + 30 + 5x = 210
90 + 8x = 210
Subtract 90 from both sides
8x = 120
Divide both sides by 8
x = 120/8 = 15

Answer:
120
Step-by-step explanation:
The absolute value is 120. Think about it on a number line, the absolute value is the amount of spaces that -120 is away from 0. Therefore, the amount of spaces -120 is from 0, is 120.
Answer:
f ^-1 (x) = 2x+28
Step-by-step explanation:
f(x) = 1/2x-14
Replace f(x) with y
y = 1/2 x -14
Exchange x and y
x = 1/2 y -14
Solve for y
Add 14 to each side
x+14 = 1/2 y -14+14
x+14 = 1/2 y
Multiply each side by 2
2(x+14)= 1/2 y*2
2x+28 = y
The inverse function is
f ^-1 (x) = 2x+28
