It Means 3×3×3=27 . The First Option Is Correct
Well, luckily it is apparent that (x-1) is a root because when x=1 the equation is equal to zero. So we can divide the equation by that factor to find the other roots.
(2x^3+9x^2+4x-15)/(x-1)
2x^2 r 11x^2+4x-15
11x r 15x-15
15 r 0
(x-1)(2x^2+11x+15)=0
(x-1)(2x^2+6x+5x+15)=0
(x-1)(2x(x+3)+5(x+3))=0
(x-1)(2x+5)(x+3)=0
So the roots are x= -3, -2.5, 1
Answer:
Step-by-step explanation:
Rule: never completely trust a diagram that comes with a geometry question. This is a case in point. The "tiny" square is actually much larger than the "larger" square.
If you are trying to find the length of the sides of the squares, the formula is
Area = side^2
3025 = side^2
Take the square root of both sides.
sqrt(3025) = sqrt(side^2)
To find the square root of 3025, do the following
Press √
type in 3025
type in =
You should get 55.
======================
The second square is done the same way
√
90.75
=
And you should get 9.526
