Question

12. Fnd the roots of the quadratic equation x2-3x-10=0.
13. All circles are
(congruent/similar).​

Answer 1

Answer:

13.similar

12. x*2-3x-10=0

x*2-2x+5x-10=0

x and 5 be common

x(x-2)+5(x-2)=0

so (x-2) (x+5)=0

take both equal to 0 and remove brackets

x-2=0 or x+5=0

so your is

x=2 or x=-5

Answer 2

Answer:

similar

Explanation:

: )because Similarity is a quality of scaling: two shapes are similar if you can scale one to be like the other, like these triangles ABC and DEF. Since all circles are of the same shape (they only vary by size), any circle can be scaled to form any other circle. Thus, all circles are similar!
