The length of the hypotenuse is 20 cm.
Answer:
the -3 is being distributed. --> the 5 stays outside till the end. multiply the 3 inside first, then the negative. and then add the 5 to the final answer
5-3(d+21) = -->> 5-(3d+21)=--->>>5-3d-21=3d-16
Step-by-step explanation:
5-3(d+21) =
5-(3d+21)=
5-3d-21=
ans=3d-16
Answer:
Since both terms are perfect squares, factor using the difference of squares formula.
(x+9y)(x−9y)
