Which type of transformation is described by (x, y) → (-x, y)? a reflection across the y-axis
a rotation of 90° about the origin
a dilation of scale factor - 1
a rotation of 180° about the origin

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

answer: our required factorization will be

(3x+4)(x²-5)

step-by-step explanation:

since we have given that

now, we will write it as :

so, we get

5(3x+4)

similarly,

here, we get,

2(3x+4)

together it becomes,

hence, our required factorization will be

(3x+4)(x²-5)
