using pythagorean theorem
a^2 + b^2 = c^2
(12x)^2 + (16x)^2 = 10^2
square each term
144x^2 + 256x^2 = 100
combine like terms
400 x^2 = 100
divide by 400 on each side
x^2 = 1/4
take the square root on each side
x = 1/2
Answer: x=1/2
I don’t know if what I did is correct but if you multiply the second one by 2 the second age might be 88.
2b^2 + 81/2 b + 4
basically 2b^2 + 16b + 49/2 b + 4
= (2b^2) + 16b+49/2b) + (4)
= 2b^2 + 81/2 b + 4
Answer: A
Step-by-step explanation:
2y - 10 > 13 y = -5
2(-5) - 10 > 13
-10 - 10 > 13
-20 > 13
False
