Answer:
soln,
write the question
=9x^2+1-6x-2×9x^2+25+9x^2+25
=9x^2+1-6x-18x^2+25+9x^2+25
=9x^2-18x^2+9x^2+1+25+25-6x
=51-6x
if(3x+1)^2 mean that (3x+1)has power of 2 and u don't have to use the formula this is the answer
Step-by-step explanation:
it's just BODMAS method
The expression that is equivalent to 0.40a is ![\frac 25a](https://tex.z-dn.net/?f=%5Cfrac%2025a)
<h3>What are equivalent expressions?</h3>
Equivalent expressions are expressions that have equal values, when evaluated or simplified
The expression is given as:
0.40a
Rewrite the above expression as a fraction
![\frac 4{10}a](https://tex.z-dn.net/?f=%5Cfrac%204%7B10%7Da)
Simplify the fraction
![\frac 25a](https://tex.z-dn.net/?f=%5Cfrac%2025a)
Hence, an equivalent expression of 0.4a is ![\frac 25a](https://tex.z-dn.net/?f=%5Cfrac%2025a)
