Let
x------> height of Leon's older brother
y------> height of Leon
Convert mixed number to an improper fraction

we know that
-----> equation A
-----> equation B
substitute equation A in equation B

Convert to mixed number

therefore
<u>the answer is</u>

DO NOT GO TO THAT LINK IT IS A VIRUS
The height of larger will be 3 cm
As,
= ∛8 cm³ * 27 cm³ / (2 cm) ³

Okay I am not 100% sure because that is an extremely confusing question. But here is what I got.
(A) 2c² = 2bc + ac/2 Given
(B) 4c² = 2bc + ac Multiplication and Distribution
(C) 4c = 4b + a Division and Distribution
(D) 4c - a + 4b Subtraction
(E) 4b = 4c - a Symmetric
Is this even a question? its 66/100 you always use the first examining over 100.... makes sense
