-5y 2 from y2 simplify these​

hey is this from ncert textbook well.i know it

so question is y²-(-5y²)

it will be. y²+5y² (minus minus will become plus)

it will be then 1y²+5y² (y² will be 1y²)

so total will be 6y²

thanks pls give me brainliest I need it to upgrade the rank

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
