Step #1: Distribute
<span><span>(1.8)(1.5x)+<span>(1.8)(−2.6y)</span></span>+(−2.5)(2x)</span>+<span>(−2.5)<span>(1.5y<span>)
</span></span></span>
you'd get: <span><span><span><span>2.7x+ −4.68y </span>+ </span>−5x </span>+ </span>−<span>3.75<span>y
Step #2: Combine like terms
</span></span><span>(<span>2.7x + <span>−5x</span></span>)</span>+<span>(<span><span>−4.68y </span>+ <span>−3.75y</span></span><span>)

The correct question in the attached figure
step 1
calculate the different volumes
a) Volume of prism square base=x*x*y=x²*y
b) Volume of the cylinder=π*(z²)*y
the combined volume of the two figures=[x²*y]+[π*z²*y]
the answer is [y*x²]+[π*y*z²]
