If the legs of both triangles are supposed to be proportional then they would be equal in length because that's what proportional means
so if the legs of one triangle are 4.5 and 1.5 then the other triangle "if proportional" would have legs with the same measurements which are 4.5 and 1.5
hope this answers your question
(7x+2)(20-3x/4) = 140x + 40 - 21x²/4 - 3x/2 = -21/4 x² + 138 1/2 x + 40
this is one of those multiplications that doesn't make the result look any simpler...
Answer:

Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>given:</h3>
<h3>to find:</h3>
<h3>let's solve:</h3>

A-5B=2x+3-5(x²-5x+1)

- distribute -5 to the parentheses:2x+3-5x²+25x-5
- rewrite:-5x²+2x+25x-5+3
- combine like terms:-5x²+27x-2
and
we are done
