They are both in standard form.
It is 5 because you have to do 12 squared minus 13 squared and then square root that which equals 5
Answer:
the answerrrrrrrrrrr is 3(x+5)^2
Answer:
8y^3+6y^2-29y+15
Step-by-step explanation:
the correct expression is
(4y − 3)(2y^2 + 3y − 5)
Given data
We have the expression
(4y − 3)(2y^2 + 3y − 5)
let us open bracket
8y^3+12y^2-20y-6y^2-9y+15
Collect like terms
8y^3+12y^2-6y^2-20y-9y+15
8y^3+6y^2-29y+15
Then answer would be
90° < 0 < 180°.
hope it helps!
